  • Applications

    HC Yellow No. 13 (CAS 10442-83-8) is an organic pigment used as a colorant in a range of material systems. It is commonly employed in coatings and paints to deliver bright yellow hues for industrial and automotive finishes. It serves as a pigment in plastics and polymer formulations (e.g., PVC, polyolefins, engineering resins) to achieve durable coloration. It is used in printing inks for packaging and graphic arts, providing a stable yellow color. It is also used in masterbatches and color concentrates for plastics processing. In textiles, it may be used for pigment coloration or printed fabrics where formulation and regulatory compliance allow.
