Description

Solvent Red 179 is a high-performance, solvent-soluble red dye belonging to the anthraquinone chemical class. This product is valued for its excellent color strength, good lightfastness, and stability in various non-aqueous systems, making it a critical component for achieving vibrant and durable coloration. It is primarily needed by manufacturers in the plastics, inks, coatings, and specialty chemical industries for coloring polymers, solvent-based inks, and industrial finishes.

Application

• Coloration of engineering plastics such as ABS, polystyrene, and polycarbonate.
• Manufacturing of high-quality solvent-based printing inks for packaging and publications.
• Pigmentation for industrial coatings, automotive finishes, and wood stains.
• Dyeing of synthetic fibers and films from the melt or solution.
• Production of colored pencils, waxes, and artistic oil paints.
• As a colorant for specialty greases, lubricants, and fuel markers.
