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.
