Description

Solvent Red 1 is a synthetic organic dye belonging to the azo class, widely recognized for its vibrant red color and excellent solubility in non-polar organic media. This compound is valued for its strong tinctorial strength and stability in various solvent-based systems, making it a critical component for precise coloration. It is primarily utilized by manufacturers in the plastics, inks, and coatings industries where consistent, non-aqueous colorants are required.

Application

• Primary colorant for solvent-based inks, including flexographic and gravure printing inks.
• Coloration of polymers and plastics, such as polystyrene, acrylics, and certain polycarbonates.
• Staining agent for microscopy and biological applications in non-aqueous preparations.
• Colorant for wood stains, lacquers, and industrial coatings.
• Used in the formulation of colored waxes and polishes.
• Marker dye for fuels and lubricants for identification purposes.
• Pigment for specialty artists' paints and varnishes.
