Description

Pigment Red 23 is a high-performance, synthetic organic pigment belonging to the azo chemical class. This versatile colorant is valued for its strong, bright red hue, excellent tinting strength, and good overall fastness properties. It is a critical raw material for manufacturers requiring durable and vibrant red coloration in a wide range of industrial and consumer products. Key industries that utilize this pigment include plastics, coatings, inks, and synthetic fibers.

Application

Pigment Red 23 is engineered for high-performance coloration across diverse industrial sectors. Its primary applications include:

• Plastics and Masterbatch Coloration: For coloring PVC, polyolefins (PP, PE), and engineering plastics, offering good heat stability and dispersion.
• Industrial and Decorative Coatings: Used in solvent-based and water-based paint systems for automotive refinish, industrial machinery, and architectural applications.
• Printing Inks: A key component in offset, gravure, and flexographic inks for packaging, publications, and commercial printing.
• Synthetic Fibers: For mass coloration (dope dyeing) of polyamide, polyester, and acrylic fibers, providing excellent wash and light fastness.
• Specialty Applications: Suitable for coloring rubber, leather finishes, stationery, and artists' colors where a vivid red is required.
