Description

Solvent Red 210 is a high-performance, oil-soluble organic pigment belonging to the anthraquinone class, widely recognized for its excellent color strength and stability. This compound is critical for providing vivid, durable red coloration in non-aqueous systems where superior lightfastness and heat resistance are required. It is an essential raw material for manufacturers in the plastics, coatings, and specialty ink industries seeking consistent, high-quality pigmentation for their products.

Application

• Primary colorant for plastics and synthetic fibers, including polyolefins, PS, ABS, and PET.
• Formulation of high-grade industrial coatings and automotive paints requiring excellent weather resistance.
• Manufacturing of specialty printing inks, particularly for packaging and security applications.
• Coloration of waxes, greases, and other hydrocarbon-based compounds.
• Pigmentation for wood stains and transparent coating systems.
• Used in the coloring of certain cosmetic products and personal care items where oil solubility is needed.
