Novel Multifunctional Coalescent for Property Improvement and Lower VOC L - Emerald Kalama Chemical
Emerald Kalama Chemical has developed a new coalescent to address challenges in the industry for improving key properties of coatings while minimizing volatile organic compound (VOC) values of waterborne latex coating formulations.  Environmental regulatory groups continue to lower VOC limits in coatings, and traditional low vapor pressure coalescents can lower VOC while improving gloss values and scrub resistance.  However, block resistance, hardness development, and dirt pickup resistance can be challenging to achieve with these materials in low PVC formulations.  Emerald’s new coalescent increases coalescent efficiency, hardness development, dirt pickup resistance, and blocking resistance even when compared to commonly used high VOC coalescent aids.  With respect to specific binders, improvement in wet edge, open time and scrub resistance values have been observed.  Emerald is continuing to develop new technologies which also contribute to improved properties in deep base formulations as well as flash rust prevention.

The Sidney Lauren Memorial Lecture - Non-Isocyanate Polyurethane Coatings Cured Via Azido-Alkyne Cycloaddition

Conventional polyurethane/polyurea polymers are crosslinked by reaction of a polyisocyanate compound with a polyol of the polyester, polyether, or polyacrylic type.  Polyurethanes offer superior mechanical properties, especially abrasion resistance, good chemical resistance, and excellent weatherability (aliphatic isocyanates only), and are used in many high-performance polymer applications, including coatings, adhesives, flexible and rigid foams, and solid elastomers. For many of these products, particularly coatings and foams, the presence of free isocyanate groups in the uncured composition is a safety and health concern due to the toxicity of isocyanates; thus, there is interest in non-isocyanate polyurethane/polyurea (NIPU) polymers that can be crosslinked by alternative chemistries.  Our research group has developed a series of NIPU polymers for coatings that cure by azide-alkyne cycloaddition.  Commercial polyisocyanate resins based on trimers of hexane diisocyanate, including allophanate (e.g. Desmodur® XP2580), isocyanurate (e.g. Desmodur N3300), and biuret (e.g. Desmodur N3200) were reacted with propargyl alcohol to produce polyurethane resins with propargyl functionality.  Various polyols, including polyether (PPG 1000), polyester (Desmophen 650), and polyacrylic (Setalux DA870) types were modified to convert their hydroxyl functionality to azide functionality.  The best performance was obtained with an alkyne component based on Desmodur XP2580 and an azidated polyol based on Setalux DA870.  Clear, high-solids two-component coatings were formulated with and without Cu(I) catalyst, employing about 5-10 wt% n-butyl acetate for final viscosity reduction.  The coatings were drawn down on steel panels (6 mils wet), the solvent was allowed to flash, and then the films were cured for 4 h at 100° C. Coating performance properties such as pencil hardness, MEK double rubs, and glass transition temperature were comparable to a conventional polyurethane control coating made from the precursor resins.  Azido-alkyne formulations in the presence of copper catalyst with reducing agent exhibited faster curing kinetics than the polyurethane control.

Rheological Study of the Effect of Surface Active Additives on the Drying of Waterborne Dispersion Paints - Clariant
A special measuring geometry, rotating at low constant angular velocity through a paint film, was developed to record the increase of torque during drying under constant temperature and humidity conditions, thus giving access to a qualitative and quantitative differentiation of additives regarding their impact on the drying behavior of the paint.  A series of additives with different hydrophilic lipophilic balance values was tested in two paints, an acrylic lacquer with a pigment volume concentration of 36.2% and an indoor/outdoor dispersion paint with a pigment volume concentration of 78.6%.  Interestingly, the additive performance was found to be dependent on the paint composition, suggesting that specific interactions between the additives and the paint ingredients are mainly responsible for influencing the drying process.  This method represents an interesting alternative for additive testing and identification of the best choice to achieve the desired impact on the drying behavior of waterborne dispersion paints.

Understanding Chemical Resistance in Epoxy Systems - Evonik
Two-component epoxy systems have proven track record for providing excellent mechanical properties, chemical resistance, and adhesion to a wide range of substrates. They are frequently chosen over other technologies especially when chemical resistance is an important attribute. Chemical resistance is required in a variety of applications from construction and infrastructure to marine and protective metal coatings, and involves various substrate surfaces in flooring, bridges, wastewater treatment plants, power plants, metal equipment, and marine ships. These assets are constantly under attacks from various chemicals such as salt water, acids, and organic solvents. Chemical resistance is critical to provide protection to maximize the service life of the assets.

A number of factors determine the type of epoxy system required for chemical resistance. Key aspects influencing the chemical resistance of an epoxy system include crosslinking density, and degree of cure. Crosslinking density largely depends on the structure and functionality of epoxy resin and curing agent, while system mobility impacts the degree of cure. Molecular modelling and analytical techniques of differential scanning calorimetry, Raman spectroscopy, and dynamic mechanical analysis shed light on the fundamental understanding of the influence of crosslinking density and degree of cure on chemical resistance. This paper will detail the results of such fundamental study.

Fine-tuning Coating Surface Control Through the Use of Modified Siloxanes - Evonik
Siloxane-based additives are critical tools in coating applications because their structures can be varied to provide a broad range of performance benefits in many types of formulations and chemistries.  Surfactants and defoamers are some of the more commonly recognized additive classes, but many other functionalities can be derived from siloxane chemistries, particularly attributes related to surface control such as flow and leveling, slip, scratch resistance, and haptic properties.  This extensive range of performance is achievable due to the broad flexibility inherent in siloxane chemistry, allowing a fine-tuned balance of compatibility, incompatibility, and surface activity.
As with many additive types, a broad range of functionalities creates many options for improvement and innovation but also presents challenges in finding the right additive and optimizing to achieve the desired performance. This presentation will attempt to clarify the general structure-property relationships that drive the performance attributes of siloxane additives and detail the continuum that exists between wetting, leveling, defoaming and slip within this chemistry class. Surface control properties and testing will be reviewed and related to recent evaluation work conducted in developing novel siloxane surface control additives.

Oil is Oil…Until It’s Not: An Investigation into the Coating Structure-Property Relationships of Various Process Oils - Firestone Building Products Company, LLC
In an effort to correlate oil industry characterization parameters with properties commonly used in the polymer/coatings industry, sixteen process oils were screened for use in a two-component aromatic polyurethane coating formulation.  A combination of viscosity and proton NMR testing was employed to successfully predict aniline point (oil industry) and cloud point (ink varnish industry) for the various oils.  Aniline/cloud point values were used to interpret oil migration behavior as well as tensile and adhesion properties of the coating films.  Cured film properties of the coatings will be presented.  These results provide a useful framework for the formulator to incorporate process oils in coating formulations.

Solvent Trapping Effect on Pull-off Adhesion of Model Epoxy-amine Coatings to Steel - USM
Solvents continue to be a large part of the surface coating industry, making it important to know how the chosen solvents and their quantities affect the final product and performance.  One of the defects seen in solventbased systems is solvent trapping.  Rapid solvent loss from a freshly applied coating could result in the surface layer forming a skin, which significantly decreases the solvent diffusion coefficient at the air interface and traps the solvent remaining in the film.  The residual solvent has significant influence on the film's properties. Primarily, residual solvent induces film plasticization, which is manifest as reduction in modulus and glass transition temperature.  Due to skin formation, these changes are noted more towards the substrate interface.  
The effects of residual solvent on interfacial properties such as adhesion are virtually unexplored.  In the absence of residual solvent, increasing film thickness leads to increased internal stress and predictably lower adhesion.  As a consequence, there is a critical thickness for any formulation above which the coating is unable to be applied because it will spontaneously delaminate.
This solvent trapping process can be modeled to predict the amount of residual solvent over a range of time and temperatures.  The present work demonstrates a reversal of the relationship in the presence of residual solvent leading to better adhesion with increased thickness and elimination of the spontaneous delamination thickness.  Numerous factors contribute to this outcome and it is the goal of this work to investigate internal stress, modulus and interfacial interactions to explain what factors contribute in what way to the solvent trapping effect on adhesion.
The coatings in this study are model epoxy-amine networks formulated to cover a range of crosslink densities and glass transition temperatures.  Material properties, cure temperature, solvent boiling point and solvent-resin affinity encompass the processing knobs available to control the residual solvent content and its distribution.  Solvents that were used include ethanol, isopropanol, butanol, di(propylene glycol) propyl ether, xylene, tetrahydrofuran and p-chlorobenzotrifluoride. At each film thickness, the films were evaluated for residual solvent content, adhesion, modulus, internal stress and glass transition temperature. Residual solvent was determined by thermal gravimetric analysis. Adhesion was quantified using the pull-off method on a MTS load frame, while tensile testing was performed on the same load frame to collect modulus data. Internal stress of formation was calculated based on substrate deflection. The glass transition temperature was quantified from the tan d peak measured via dynamic mechanical analysis. These studies will help with the prediction and planning of interfacial adhesion properties of coatings and better formulation skills.

The Use of Engineered Silica to Enhance Coatings - Evonik
The field of coatings technology has utilized many forms of silica-based particles in the last 70 years. This large, varied class of fillers is generically broken into two categories of crystalline and amorphous morphology.  With ongoing scrutiny and sensitivity in the coatings industry to move towards less hazards in the workplace, greater emphasis is placed on suitable amorphous technology to replace crystalline silica technology.  Amorphous silica character is highly adaptable and flexible to be modified in both powder and pre-dispersed forms, and numerous engineered types of technologies have been developed to provide functional solutions to many coatings problems.
Amorphous silica technology has been developed to address functionalities including rheological control, suspension of pigments and fillers, reinforcement of coatings film, impart scratch resistance, impart hydrophobicity /anti-corrosion benefits, impart oleophobicity, as carriers of trace actives into coatings for homogenous distribution, flow control and charge enhancement of powdered coatings, and gloss reduction of liquid systems.  Particle technology and modification will be addressed and performance attributes highlighted for each of the types of tailor-made modifications.  A short discussion of the importance of proper dispersion and homogenous distribution within a
coatings matrix will be included.
This paper will address how amorphous silica technology is differentiated and engineered to create specially tailored solutions to enhance the performance of coatings and also highlight the latest technical developments in this field.

Bio-based Pigments and Super Transparent Colorants for Durable Finishes - Clariant
Earlier, both azo and polycyclic organic pigments were based on carbon (non-renewable sources) driven raw materials. Now with technological improvements, many of the high performance polycyclic pigments such as quinacridone are synthesized from bio-based raw materials.  These pigments have the same clean shades, high transparency, and high performance necessary for brilliant automotive finishes, but with much lower carbon footprint.
Several super transparent colorants have been developed based on chlorine-free pigments.  With optimum milling and additives, these colorants have excellent shelf stability, and compatibility in most solvent-based systems for high performance coatings.  For metallic shades in electronics and motorcycle finishes, these colorants offer no issues with waste incineration.  Small to large batches can be easily formulated with these stable and very chromatic colorants.
UV curable transparent colorants suitable for automotive simulated interior wood finishes will also be discussed.  These highly stable and durable colorants have very good shelf stability, and their compatibility with most reactive systems is also excellent, thus offering almost universal appeal.  In addition, these colorants are registered in most countries.
The bio-based pigments and super transparent colorants will be part of this paper dedicated for the industrial, automotive and other unique finishes.

Color My World! New Tools for Improving Colorant Acceptance in Waterborne Architectural Coatings - Evonik
Claude Monet once commented that “Color is my day-long obsession, joy and torment” – a sentiment that resonates with formulators of waterborne architectural paints who need to design base paints that can accept a variety of liquid colorants, enabling a paint line with the broadest possible color palette. 
With the advent of point-of-sale (POS) tinting systems, many paint manufacturers now produce only a small number of base paints to which the colorants are added at the store.  This allows paint manufacturers and stores to manage inventories by stocking fewer materials, and it significantly decreases the amount of unused paint that goes to waste each year.  However, the colorants used in POS tinting systems must have excellent compatibility with different base paints to ensure consistent, reproducible colors under all conditions. This remains one of the toughest challenges facing the waterborne architectural paint formulator today.
Difficulties occur when additives used to stabilize the pigments in the colorant interact with additives in the base paint, causing loss of pigment stabilization and flocculation. This leads to an immediate or gradual color change that can be observed in a “rub-out” test in the laboratory. “Problem pigments” like PV23, PBk7 and PB15:3 give rise to the most challenges with regards to colorant acceptance. This paper will describe the mechanisms involved in colorant stabilization and, using chemical structure-property relationships, explain how specific surface active agents can be used within the base paint formulation to prevent destabilization of the colorant, ensuring that it performs as intended.

Novolak Resins in Powder Coatings - Georgia Pacific Chemicals
This study was performed to understand the effect of a phenolic resin’s molecular weight upon the film properties of epoxy:polyester hybrid powder coatings.  Three phenolic resins with softening points of 98 - 102 °C, 108 -110 °C and 118 - 122 °C were studied.  Each resin had a free phenol content of less than 0.2%.  Differential scanning calorimetry was used to determine the activation energies of crosslinking reactions, powder collapse temperature and glass transition temperature of cured films.  Fourier transform infrared analysis was used to follow crosslinking processes as a function of catalyst concentration by monitoring the decrease of oxirane concentration at 375 °F for 30 minutes.
The relationship between phenolic molecular weight and torque experienced in the extruder will be presented. Initial results showed that phenolic modified coatings require lower temperatures to achieve torque values equivalent to a control coating, thus demonstrating potential energy savings during extrusion. Film properties of coatings cured at 375 °F for 30 minutes will be presented that show the influence of the phenolics’ molecular weight.

Advances in Focused Ion Beam Technology for the Characterization and Analysis of Polymer, Ceramic, and Metallic Coatings - Thermo Fisher
Scanning electron microscopy (SEM) and focused ion beam (FIB) techniques, together commonly known as a DualBeam, have long been a critical component for the analysis of polymer, ceramic, and metallic coatings.  Recent advances in ion beam technology have opened the practical application space to the processing and data collection from larger areas and greater volumes.  Due to throughput limitations, the common site-specific cross-sections were no larger than 50 - 100 µm; volumes for three-dimensional (3D) analysis measured in the tens of cubic microns.  The development and incorporation of the plasma focused ion beam (PFIB) has increased this by an order of magnitude, making up to 1 mm site-specific cross-sections a common feature.  Analytical volumes, including 3D imaging, 3D energy dispersive X-ray spectroscopy, and 3D electron backscatter diffraction, have also expanded significantly.  These greater areas and volumes have improved the analysis of large features and increased the statistical relevancy of DualBeam data, aiding decision-making based on information derived at the micro- and nanometer scales.  This paper will discuss the advances in PFIB technology and provide application examples of polymer, ceramic, and metallic coatings.

Balancing Performance in Interior Waterborne Coatings - Arkema
It is no surprise that waterborne coatings dominate the North American architectural coatings segment.  The residential repaint and remodel market, which includes do-it-yourself (DIY) and contractor paints, accounts for over 60% of that segment.  For those applications, there is a huge demand for balanced performance.  These challenging performance targets are reflected in the many product label claims that paint manufacturers highlight on those consumer products.  Through a simple survey of those claims from 14 top tier paint lines, we see that stain resistance, durability, and one-coat hide are three of the most highly valued performance benefits.  The first portion of this paper will summarize some benchmark testing on eight top tier product lines taken from the consumer segments, wherein we focus on stain resistance, which is evaluated by testing washability to household stains, and durability, evaluated by testing ASTM scrub resistance.  That testing revealed some performance gaps in these products, which will be highlighted.  The second portion of this paper will outline our work toward developing an emulsion polymer that provides a balance of washability, scrub resistance, and tint strength, which is related to one-coat hide.  We have identified methods for improving washability and scrub resistance through the proper selection of bulk monomer, as well as through the proper selection of functional monomer type and level. Additionally, the balancing of functional monomer and process conditions has led to a very powerful lever for improving tint strength.  Another component of emulsion polymers, the emulsifying/ stabilizing surfactant, is also responsible for stain resistance.  Lastly, emphasis will be placed on the role of the various components of a waterborne paint formulation on washability.  Those resin concepts were used to design an emulsion polymer for use in both flat and semigloss paints, the full performance balance of which will be presented in this paper.

Microscopy Characterization of Coatings - Zeiss
Coatings have a broad range of applications in industries like pharmaceuticals, automotive, medical devices, textiles, oil and gas, aerospace and defense, food and packaging, and consumer optics, thanks to their role as functional, high performance or protective materials.  To meet stricter environmental regulations, increase sustainability and meet new customer demands, improving the
design of coatings and optimizing their performance is of critical importance to further advance innovation while remaining competitive in price. In addition, it is also important not only to develop novel materials, but also to maintain and ensure the quality of coatings while reducing the commercialization cycle.
Researchers rely on characterization techniques that help them understand the relationships between structure, properties, performance and process of coatings. Characterization includes 2D analytical solutions, 3D non‐destructive imaging and in situ capabilities, as well as advanced software packages that equip researchers to become pioneers in this field and expand the portfolio of coatings to new markets.
Characterization (microscopy, modelling and simulation, image analysis and spectroscopy) is used to determine the chemical composition as well as mapping contaminants and defects that influence the performance of coatings. In addition, these tools help researchers understand the structure and morphology, adhesion failure, as well as how the process variables influence the material properties. From looking at cross sections, delamination, corrosion to extracting actionable information from micrographs (thickness measurement and particle size distribution) and obtaining texture and roughness information, microscopy solutions provide new insights. In addition, uniformity and coverage of coatings, the presence of pores, microstructure and texture, segmentation and analysis of different features of interest as well as topography investigations can be determined.
This paper illustrates a case study on how optical and confocal microscopy, focused ion beam and correlative microscopy is used by ZEISS Vision R&D to make sure that new customer demands are met while keeping the quality and great performance of coatings.

Photosensitive HAPTIC Coatings for Athletic Footwear & More - HAPTIC
Waterborne high-solid 3D HAPTIC coatings are enjoying a big market success in recent years.  Its main application field is athletic footwear.  Exciting multi-color effects on multiple 3D coating levels in combination of sensational touch effects and high performance features allow totally new freedom of functional design.
Now new photosensitive HAPTIC coatings are being introduced to the markets.  HAPTIC coatings are based on fully waterborne PUD resins with high elasticity, flexibility and superior bonding properties and are usually applied on textile substrates.  Based on nanoscale oxidized graphene particles, i.e., graphene oxide (GO) nanoparticles, highly photosensitive coating layers were developed.  The GO-doped HAPTIC layers show high transparency and are nearly colorless.  When the GO-doped coatings are exposed to natural sunlight or artificial UV light, the GO nano-layers start a chemical reduction process and dark black graphene nano-layers are produced.  Relatively large sp2 islands will be formed totally changing the absorption properties of the coatings and turning over time into dark black color.  By masking devices, the coating on athletic footwear could be partially exposed to UV light and design patterns could be created by selective UV exposure.  Furthermore, the GO-doped HAPTIC coatings could be further pigmented with standard pigments well known in coating industry or with iridescent special effect pigments.  During the time of UV exposure, creative color effect changes could be achieved changing the appearance of a surface over time.
Following the new mega trend of mass individualization of consumer products, these photosensitive coatings could open up opportunities for point-of-purchase individualization of athletic footwear and other products by using digital cut masking papers and UV radiation devices directly in the shop environment. Another option could be creating consumer products that will change color over time when used in outdoor sunshine environment.

After working in coating labs for over 45 years, I have seen a lot of changes. This presentation will highlight some of the changes (government regulations, raw materials, etc) and the reasons for them. In some cases, the changes caused more problems than they helped. One example is OSHA. Protecting employees was needed. But some of the original regulations would come as a surprise to most people who were not around then. The same can also be said of the original air pollution regulations.

The Effect of Microfibrillated Cellulose on Mechanical Properties and Performance of Acrylic Elastomeric Roof Coatings - Borregaard
Waterbased acrylic elastomeric roof coatings have become a hot topic lately.  One of the reasons is that they reduce the heat absorption of the buildings when compared to the traditional asphalt roofs.  In addition to heat prevention and energy savings, acrylic roof coatings protect the underlying material from water, UV radiation, chemicals and wear.  Waterbased acrylic roof coatings are typically thickened with cellulosics and associative thickeners.  Their use can often lead to challenges in both water resistance and absorption of the coating.  In addition, the control of syneresis and sagging is often challenging.  Microfibrillated cellulose (MFC), a biobased and multifunctional product made from cellulose, consists of fibrils with lateral dimensions in the nanoscale and lengths up to micron scale.  These strong and rather stiff fibrils are able to form strong films (tensile strength up to 210 MPa).  Once MFC is added to a paint, a noticeable effect is usually seen on the mechanical properties of the final coating.  In addition to the effect on mechanical properties, the unique rheological properties allow formulation of stable and easily applicable paints.  The high yield stress of MFC coatings prevents settling of heavy particles as well as floating of hollow microspheres, whereas the strong shear thinning allows the spraying of thick formulations.  Their exceptional thixotropic behavior leads to excellent sag resistance combined with good levelling.  The aim of this work was to evaluate the effect of MFC on the key properties of acrylic elastomeric roof coatings such as tensile strength, water resistance, mud cracking and adhesion to metal and concrete surfaces.  Commonly used thickeners were used as references.  To deepen the understanding of the impact of MFC on tensile strength and elongation and the relationship between these two parameters, different fibrillation degrees and dosage levels of MFC were used.  We will demonstrate how MFC increases the tensile strength of elastomeric acrylic roof coatings without sacrificing its elongation and overall performance.

Carbon Capture Coatings - Reactive Surfaces
Coatings can make a significant contribution in combating the problem of increased atmospheric carbon dioxide levels and detrimental impacts of climate change.  Ocean-bound algae exist primarily as a thin layer that spreads over vast oceans surfaces and currently account for most (70 - 80%) of the earth’s photosynthetic conversion of carbon dioxide (CO2) into oxygen (O2).  We have been able to mimic this thin layer of horizontal algae in land-based platforms, while minimizing the footprint of land needed by converting the system into coated vertical arrays.  Natural polymer gels have long been used to support the growth of living cells.  We have designed and prototyped translucent coatings that retain high levels of moisture (> 80% water content) when applied over large vertical surfaces and produce usable products within the coating that can be recovered for added market value.  This was achieved using an algae engineered to express genes from a bacterial cellulose producer.  As these algae are photosynthetic, this strain produces cellulose from captured CO2 and sunlight.  We demonstrate that these genetically-modified algal cells are not only viable in the coating system for months, but they also actively capture CO2 and produce cellulose.  Furthermore, the current coating can be removed from the vertical substrate and easily disassociated, releasing the cellulose for collection.  Other algae have the potential to be genetically modified in a similar manner, whether to produce usable products such as cellulose and other polysaccharides (or protein or fatty acids) or to tailor the host algae for different application conditions, such as arid and/or high light conditions.  This research opens up a new field by merging genetically engineered microbes with coatings to produce usable and harvestable products while also sequestering CO2 in the process.

Applications of Evolutionary Operation (EVOP) for the Coatings Industry - Huber
The use of Design of Experiment (DOE) methodologies in the industrial setting has gained a lot of interest in recent years and is being used more frequently.  There are several types of designs that can be used to decrease variation, improve quality and reduce costs, e.g., Taguchi Robust Product Design, Response Surface Methods, etc.  Typically, DOE is limited in industrial manufacturing to designs with less than 16 runs.  The results from these studies do not always account for long-term variation that occurs at the full-scale production level given the differences in process variation, raw materials, etc. over time.  One technique that attempts to account for long-term variation using the results of designed experimentation results is Evolutionary Operation (EVOP).  EVOP was first proposed by Box (1957).  The application of this technique in the wood products industries will be discussed with benefits and shortcomings highlighted.

New Development for Zeta Potential Measurement of Coatings for Stability Characterization - DataPhysics
A new device for measuring zeta potential of coatings was recently developed by DataPhysics Instruments in collaboration with Leibniz Institute of Polymer Research Dresden (IPF).  Zeta potential is a measure of the electrical potential at the interface between a solid surface and a liquid, and is an important indicator of the stability of colloidal dispersions.  In a dispersion, the magnitude of the zeta potential provides an indication of the degree of electrostatic repulsion between adjacent, similarly charged particles.  When the particles or molecules are small enough, a high zeta potential will indicate a greater stability and the dispersion will resist aggregation.  A lower zeta potential means that attractive forces between particles may be stronger than repulsive forces, causing the dispersion to break apart and flocculate.  Thus, colloids with a higher zeta potential (negative or positive) are electrically stabilized while colloids with lower zeta potential tend to coagulate or flocculate.
For some years now, IPF has been recognized as a leader in the study of zeta potential measurements related to colloidal systems, the characterization of electrical properties of surfaces, and in the monitoring of chemical reactions. IPF has generated significant ideas for improvement of these test methods and for major enhancements in commercial zeta potential instruments. The unique, new device described in this paper uses the streaming potential principle for electro-kinetic measurements and for the first time, uses innovative bidirectional pressure cycles created with an oscillatory pump. This novel approach yields higher stability of the zeta potential measurements by employing twenty (20) pressure cycles per measurement compared to the traditional four (4) cycles. The new device also includes both temperature control and allows for purging of the sample chamber with inert gas. The teamwork of IPF scientists and expert engineers from DataPhysics Instruments has resulted in a zeta potential device with greatly improved capabilities for broad range of applications including characterization of the stability of coatings.

Redox Optimization for Emulsion Polymer Chase: New Approach to Reduce VOC’s, Cycle Time, and Cost - Brueggemann
Reduction of residual free monomer is required in the manufacture of latexes to reduce VOCs.  This has become even more critical as consumers are demanding coatings with reduced odor. Conventional post-polymerization chase techniques using reducing agent/oxidizer redox pairs can achieve low levels of residual monomers, but this can increase production time, add cost and reduce production capacity.  A post-polymerization redox optimization study was conducted on a production latex made with a thermal persulfate to initiate the main polymerization.  The monomers used were methyl methacrylate, styrene, methacrylic acid, and butyl acrylate.  Various redox combinations were tested in the post-polymerization stage at different dosage levels and feed rate to minimize redox quantity, residual monomers, and time.  It was found that the right redox pair, fed simultaneously at high concentration, was capable of eliminating free monomer down to non-detectable levels in 15 minutes.  This can enable up to 75% cycle time reduction for post-polymerization.

Impact of Silane Crosslinkers on the Solution Stability of Latex and Ultimate Film Properties - DyStar
Silanes have been shown to improve film properties of resin systems when they are reacted into the resin or incorporated into a resin solution as additives.  The improved properties result from their unique functionality that allows for inter-polymer crosslinking and chemical bonding to many substrates. Due to the high reactivity of silanes, especially towards hydrolysis and self-condensation, their use as additives in water-based systems can be limited.  Therefore, it would be desirable to successfully disperse the silane additive into water-based resin systems and have that system remaining stable.  Work was done to investigate the structure, functionality and processing conditions to successfully disperse silanes in latex resin.  Application work done to test the impact of these silane additives in clear resins and paint formulations has shown advantages of the dispersed silanes versus standard latex in fully formulated systems.  The authors reason that the property enhancements afforded by this new technology should be applicable to direct-to-metal, architectural and industrial maintenance coatings.

Room Temperature Cured Corrosion Protection of Metals with Novel 2K Waterborne Organofunctional Silane Pretreatments - Evonik
As global environmental regulations continue to tighten restrictions on the use of well-established metal surface pretreatment processes such as chromate treatment and phosphatization, the need for environmentally-friendly corrosion protection systems has never been greater.  While one promising alternative to this worldwide regulatory issue is waterborne, heavy metal-free silane pretreatments, this technology often requires significantly high curing temperatures (ranging from 80 – 200 °C) to achieve sufficient corrosion protection of metals.  Although many industries around the world are moving away from hazardous metal surface pretreatment processes due to global regulations and consumer awareness, a majority of these industries do not have the capabilities or cost positions to replace this existing technology with environmentally-friendly alternatives that require elevated temperature curing procedures.  In this work, we demonstrate for the first time that a 2K system comprising of a hydrophobic diamino-functional silane oligomer and a waterborne sol-gel silane provides excellent corrosion resistance, alkaline resistance, and weatherability to metal surfaces (primarily aluminium alloys and steels) when cured at room temperature.  By incorporating this hydrophobic diamino-functional silane oligomer into the waterborne sol-gel silane, the hydrophobicity, surface passivation, and crosslinking density of the system is vastly enhanced - even in the absence of an elevated temperature cure.  These new findings demonstrate significant progress in overcoming the most prevalent obstacle in the use of waterborne silane technology as an environmentally-friendly alternative for corrosion protection of metal surfaces.  Industries and markets that previously could not use environmentally-friendly metal pretreatment technology due to the elevated temperature curing requirements can now explore this field with a higher probability of successfully replacing existing hazardous metal pretreatment technology.

High Gloss Direct-To-Metal Waterborne Coatings - AGC Chemical
We evaluate corrosion inhibitors with blends of various waterborne acrylic and FEVE (fluoroethylene vinyl ether) resins for improved adhesion and appearance after UV exposure and corrosion testing when applied as DTM (direct-to-metal - without primer) coatings.  Accelerated outdoor UV exposure, electrochemical impedance spectroscopy, and cyclic salt fog/UV exposure were used to evaluate corrosion resistance along with gloss and color retention.

Blending Hydrogel Particles into Various Anti-Corrosive Coatings for Water Mitigation and Performance Property Retention During Environmental Exposure - USM
Coatings protect metal substrates through a variety of processes depending on material type(s), exposure time, and environmental severity, specifically water, oxygen, and electrolytes.  Most coating systems resort to designing torturous pathways within coatings or developing different levels of hydrophobicity to detour water; however, regardless of the polymer, they are not completely impermeable to these corrosion-supporting elements.  Therefore, understanding the mechanism of water equilibrium and saturation location in relation to the polymeric material choices requires innovative research tools and new understandings of how polymer variables affect the subtleties of water management.  Literature speculates that localized hydrophilic addition in polymer-based water management films provides a means to force disruptions in traditional water management by directing the spatial location contribution.  The hydrogel particles facilitate distinct domains with concentrated ionic content, hydration particle diameter, and provide specific locations for the collection of water which perturbs the performance properties.
Hydrogel particles were incorporated into three resin systems, specifically a phenoxy, polyurethane, and commercial epoxy-amine, to understand how hydrophilicity changes the performance properties. The hydrogels were blended at 1 wt% on solids for all coatings and characterized by measuring diffusion patterns, resulting changes in modulus and internal stress, and corrosion analysis. Despite the chemistry of the coatings, networks with hydrogel particles had a 10% by weight higher bulk saturations than their control counterparts. However, this increase in saturation was not detected at the substrate-coating interface with ATR-FTIR spectroscopy, where for example, the phenoxy system exhibited 48% less water at the interface when exposed to deionized water in the presence of hydrogel particles. Mechanical adhesion was also increased by blending hydrogel particles into the resins and is suspected to retain adhesion when exposed to environmental conditions. Continued investigation of property retention included internal stress, cyclic adhesion and void formation, and positron annihilation lifetime spectroscopy.

Slippery, Smooth or Sticky? Using Tribo-Rheometry to Characterize Sensory Perception of Coated Surfaces - TA Instruments
Tribology capabilities on commercial rheometers have enabled measurements at lower load forces, friction forces and sliding speeds than industrial tribometers.  These “soft tribology” measurements have proven useful in predicting sensory properties such as mouthfeel or texture.  As tribology is a measurement of surface interactions, the results are highly dependent on test fixture material.  To detect differences perceived by human touch, it is beneficial to select materials that mimic the surface properties of our skin.  Sensory perception is also a consideration for high-contact solid surfaces like personal electronics, or coatings for surfaces in the home, such as matte or gloss paints. Tribology can evaluate the “feel” of these solid surfaces, with appropriate fixtures.  The measurements presented compare steel fixtures with surfaces modified to better mimic skin properties.  An optimum surface material will provide differentiation between samples and minimize variability between measurements.

Turning Digital to Dollars
Abstract 
The specialty chemicals industry is a great example of a legacy market that is ripe for a digital awakening. While we are still at the dawn of digital in coatings, organizations that are driving business decisions based on data are already seeing signs of success and leadership.
In this session we will provide a framework that will help you:
  • Assess where you are on the digital adoption curve
  • Get checklists for gap analysis, project prioritization and vendor selection
  • Connect digital initiatives to operating benefits.
We will then apply the framework to two use cases: 1) cost efficient formulation and 2) enabling growth through M&A.

Quantifying Corrosion at the Interface of Coated Steel and Identifying the Major Properties from Polymer Coatings that Mitigate the Corrosion Process in the Presence of a Defect During Immersion in Saline Solution -
Coatings mitigate corrosion on assets in marine environments by acting as barriers to aggressive molecules while maintaining adhesion to the asset.  Eventually, the coatings are breached or defects develop in the coatings that have the potential to act as breaches.  The performance of breached coatings no longer depends on barrier properties; instead, it depends on the adhesion strength at the polymer-substrate interface and resistance to substrate dissolution (corrosion).  Identifying polymer properties that govern the mitigation of corrosion at this polymer-substrate interface is essential to develop future corrosion control coatings.  Analysis of cathodic disbondment at the polymer-substrate using the unaided eye, scanning acoustic microscopy, fluorescence microscopy, and electrochemical analysis techniques has been reported.
Currently, literature is void regarding means to detect the earliest onset of coating failure using a non-destructive method and identify the major polymer properties that govern the mitigation of the corrosion process at the polymer-substrate interface. Confocal laser scanning microscopy (CLSM) and electrochemical frequency modulation (EFM) were employed to obtain time-lapse quantifiable acquisitions of thermoset and thermoplastic polymer clearcoat systems in the presence of an intentionally placed macroscopic breach while immersed in saline solution. CLSM enabled us to quantify the variability of delay time for micro-blister initiation, velocity of micro-blister growth from a defect, and initiation of substrate dissolution at the polymer-substrate interface. Via EFM analysis, we were able to measure the current induced by the corrosion process (e.g., micro-blistering and substrate dissolution) at the polymer-substrate interface. CLSM-EFM time-lapse acquisitions were conducted simultaneously to identify the onset of micro-blistering and substrate dissolution at the polymer-substrate interface to deconvolute the EFM signal from the corrosion process. The EFM corrosion analysis was vetted as an industrially accessible technique to evaluate a coating’s corrosion mitigation performance in the presence of a breach at the polymer-substrate interface for both clear and pigmented coatings during immersion.

Promoting the Film Formation and Flexibility of an Asphalt Emulsion Sealer with the Addition of Fibrillated HDPE - MiniFiber
As a follow-up study to a previously reported increase in film flexibility, the film formation at temperatures from 45 to 115°F of films of an asphalt emulsion based driveway sealer with and without the post-addition of fibrillated high-density polyethylene fiber has been investigated. Utilizing six different grades of synthetic fiber, the nominal diameter and the nominal length of the fiber varied from 5 to 15 microns and from 100 to 900 microns, respectively. The resulting propensity of film formation has been shown to generally increase with fiber size; small fiber promoting less film formation than medium or large fiber. In addition, the resulting film formation has been shown to generally increase with fiber application rate; an increasing film forming trend from 0.5% to 1% to 2% fiber. Furthermore, a strong correlation between film formation and the ultimate elongation of the film has been observed.

Production, Characterization and Performance Evaluation of Cardanol Acetate in Alkyd Paints - Nnamdi Azikiwe University Awka
The utilization of cashew nut shell liquid (CNSL) is currently being focusd on by chemical industries, as they are one of the most important renewable platform chemicals due to their universal availability, inherent biodegradability, low cost, and excellently environmental friendly (i.e. low toxicity toward humans). These natural properties are now being taken advantage of in research and development, with vegetable oil derived polymers/composites, used in numerous applications including paints and coatings, varnishes, adhesives, brake lining, and biomedical. The percentage yield of CNSL obtained was found to be 85.85%. Experimental results showed that CNSL contained mainly phenolic compounds such as cardanol, cardol, anacardic acid and 6- methyl cardol. Cardanol was isolated using methanol and ammonia solution as the solvents in a ratio of 16:5. The percentage yield of cardanol obtained was 75.53%. The cardanol obtained and cardanol acetate synthesized was characterized in terms of viscosity, specific gravity, moisture content, pH, iodine value using international standard methods. The functional groups present in the raw CNSL, cardanol and cardanol acetate was determined using FTIR spectroscopy. Results showed that the CNSL contained functional groups of both saturated and unsaturated fatty acids that are essential in oil, OH free bond of alcohols, phenols; O-H stretch of alcohols, phenols, amines, carboxylics and C=C stretch of alkyne, alkenes and the presence of C=O stretch of functional group which was a characteristic of the ester. The cardanol acetate synthesized was used as a reactive diluent at varying concentrations to formulate alkyd paints. The properties of the formulated paint samples evaluated are viscosity, specific gravity, drying times hardness and thickness of dry paint films and paint film gloss. Results showed that the paint viscosity decreased with increases in the percentage cardanol acetate incorporated into the system. The dry paint films were generally hard and the thickness of the dry paint films were in the range of 0.20 – 0.25. The paint dry times increased with increases in the reactive diluent incorporated into the system. The dry paint films were generally glossy. The coating system formulated from the synthesized cardanol acetate was less VOC, non-toxic, good media resistance and environmentally friendly and can be utilized for both architectural and industrial coatings.
