  • Applications

    Pigment Yellow 3 (CAS 6486-23-3) is an organic yellow pigment used broadly as a colorant in a range of industrial formulations. In coatings and paints, it provides durable yellow coloration for architectural and industrial coatings, including automotive finishes. It is commonly dispersed in plastics and polymer formulations to impart stable yellow hues to polyolefins, engineering polymers, and other plastics. It is employed in printing inks and graphic arts formulations, including packaging inks, where color stability and brightness are important. It can also be used as a colorant in adhesives and sealants. Its use may be subject to local regulations and formulation limits for diarylide-type pigments; always verify compliance in the target market.
