Description

Pigment Red 177 is a high-performance, anthraquinone-based organic pigment known for its excellent color strength and durability. This pigment is valued for its clean, bluish-red shade and outstanding fastness properties, making it a critical component for demanding applications. It is primarily used by manufacturers in the plastics, coatings, and specialty printing ink industries seeking reliable and vivid coloration.

Application

• Plastics Coloring: For coloring engineering plastics (e.g., ABS, PS, PC), polyolefins, and PVC, offering excellent heat stability and dispersion.
• Industrial Coatings: Used in automotive, coil, and powder coatings where high weatherfastness and chemical resistance are required.
• Printing Inks: Formulation of high-grade offset, gravure, and flexographic inks, particularly for packaging and publications.
• Masterbatch Production: A key colorant for creating concentrated pigment preparations for the plastics industry.
• Synthetic Fibers: Mass coloration of fibers like polyamide and polyester during the spinning process.
• Artists' Colors: Used in the manufacture of high-quality artists' paints and pigments due to its permanence and hue.
