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.
