Description

Pigment Red 176 is a high-performance, synthetic organic pigment belonging to the Naphthol AS pigment class, valued for its excellent color strength and durability. This pigment is engineered to provide a bright, bluish-red shade with outstanding lightfastness and weather resistance, making it a critical component for long-lasting coloration. It is primarily sought after by manufacturers in the coatings, plastics, and printing ink industries who require reliable and vibrant red pigments for demanding applications.

Application

• Industrial Coatings: Used in automotive OEM and refinish paints, industrial machinery coatings, and architectural paints for its durability and color stability.
• Plastics Coloring: Ideal for coloring PVC, polyolefins (PP, PE), and engineering plastics, offering good dispersion and heat stability during processing.
• Printing Inks: A key component in solvent-based, water-based, and UV-curable inks for packaging, publication gravure, and flexographic printing.
• Masterbatch Production: Supplied as a high-concentration colorant for creating standardized plastic color masterbatches.
• Synthetic Fibers: Employed in the mass coloration of fibers like polypropylene and polyamide.
• Specialty Applications: Suitable for artists' colors, leather finishes, and other applications requiring a vivid, permanent red hue.
