Description

Solvent Red 52 is a high-purity, synthetic organic colorant belonging to the class of solvent dyes. This product is valued for its intense red hue and excellent solubility in non-polar to moderately polar organic media, making it a critical component for imparting color in specialized industrial applications. It is primarily utilized by manufacturers in the plastics, ink, and specialty coatings industries where consistent color strength and stability are paramount.

Application

• Coloration of plastics and polymers, including polystyrene, acrylics, and polycarbonate.
• Manufacturing of printing inks, particularly for specialty and security applications.
• Production of industrial coatings and wood stains requiring vibrant, transparent red shades.
• Coloring of waxes, lubricants, and petroleum products for identification and branding.
• Used as a colorant in ballpoint pen inks and other specialty writing fluids.
• Potential use as a staining agent in microscopy or as a tracer in non-aqueous systems.
