Description

Solvent Red 118 is a high-performance, oil-soluble diazo dye renowned for its intense and stable red coloration. This compound matters for its excellent solubility in non-polar organic media, providing consistent and vibrant hues in demanding industrial applications. It is primarily needed by manufacturers in the plastics, printing inks, and coatings industries seeking reliable colorants for polymers, resins, and specialty inks.

Application

• Coloration of plastics and polymers, including polystyrene, ABS, and polycarbonate.
• Manufacturing of high-quality printing inks, particularly for specialty and industrial marking applications.
• Pigmentation for industrial coatings and wood stains requiring oil solubility.
• Coloring of waxes and greases for identification and aesthetic purposes.
• Production of colored lacquers and varnishes.
• Tinting of fuel and lubricant dyes for product differentiation.
• Use in ballpoint pen inks and other specialty writing fluids.
• Coloration of synthetic fibers during the melt-spinning process.
