Description

Pigment Red 175 is a high-performance, organic synthetic pigment belonging to the benzimidazolone class, valued for its excellent color strength and durability. It is a critical component for achieving vivid, long-lasting red hues in demanding industrial applications. This pigment is essential for manufacturers in the coatings, plastics, and specialty inks industries who require superior weatherfastness, heat stability, and chemical resistance in their colored products.

Application

• Industrial Coatings: Used in automotive OEM and refinish paints, coil coatings, and heavy-duty industrial finishes for its outstanding lightfastness and weatherability.
• Plastics Coloring: Ideal for coloring engineering plastics (e.g., PVC, polyolefins, ABS) where high-temperature processing stability is required.
• Printing Inks: Employed in high-quality packaging inks, decorative laminates, and other specialty printing applications demanding color consistency.
• Masterbatch Production: A key ingredient for creating concentrated color masterbatches used in plastic extrusion and molding.
• Synthetic Fibers: Used in the mass coloration of synthetic fibers like polyamide and polyester.
• Artists' Colors: Found in high-grade professional artists' paints (oils, acrylics) due to its purity and color properties.
