Description

Pigment Yellow 6 is a high-performance, synthetic organic pigment belonging to the diarylide yellow class. It is valued for its excellent color strength, good lightfastness, and strong opacity, making it a critical component for achieving vibrant and durable yellow hues. This pigment is essential for manufacturers in the coatings, plastics, printing inks, and specialty colorant industries seeking reliable and consistent coloration.

Application

• Industrial and Decorative Paints & Coatings: Used in solvent-borne and water-borne systems for automotive refinishes, industrial machinery, and architectural paints.
• Plastics and Masterbatch Coloring: Imparts stable yellow color to polymers like PVC, polyolefins (PP, PE), and engineering plastics for consumer goods, packaging, and automotive parts.
• Printing Inks: A key pigment for offset, flexographic, and gravure inks, particularly in packaging and publication printing.
• Specialty Applications: Suitable for coloring textiles, leather finishes, and artists' colors where high tinting strength is required.
