Description

C.I. Pigment Yellow 62:1 is a high-performance, calcium-based azo pigment known for its excellent lightfastness and heat stability. This pigment is valued for providing clean, bright yellow shades with strong tinting strength and good chemical resistance. It is primarily used in demanding industrial applications where durability and color consistency are critical, such as in the coloration of plastics, masterbatches, and high-quality printing inks.

Application

• Plastics and Masterbatch Coloration: For coloring polyolefins (PP, PE), PVC, and engineering plastics, offering excellent dispersion and heat stability during processing.
• Printing Inks: Used in solvent-based, water-based, and offset printing inks for packaging, publications, and decorative prints.
• Industrial Coatings: Suitable for coil coatings, automotive refinishes, and general industrial paints requiring good weatherability.
• Synthetic Fibers: For mass pigmentation of fibers like polypropylene and polyamide.
• Rubber and Elastomers: Provides stable coloration for technical rubber goods and footwear.
• Leather Finishing: Used in pigmented finishes and coatings for leather goods.
