Description

Pigment Red 169 is a high-performance, synthetic organic pigment belonging to the diketopyrrolopyrrole (DPP) class, valued for its excellent color strength and durability. It is a critical component for achieving vivid, long-lasting red shades in demanding applications. This pigment is essential for manufacturers in the coatings, plastics, and specialty printing ink industries seeking superior weatherfastness and chemical resistance.

Application

• Industrial Coatings: Used in automotive OEM and refinish paints, coil coatings, and industrial finishes for outstanding exterior durability and gloss retention.
• Plastics Coloring: Imparts brilliant, heat-stable red coloration to engineering plastics, PVC, polyolefins, and synthetic fibers.
• High-Performance Inks: A key pigment for solvent-based and UV-curable printing inks, including packaging, decorative, and security inks.
• Masterbatch Production: Supplied in powder form for the creation of concentrated color masterbatches for the plastics industry.
• Artists' Colors: Employed in the formulation of high-quality artists' paints and pigments due to its purity and chromatic properties.
