Description

Solvent Brown 43 is a synthetic organic dye belonging to the solvent dye class, identified by CAS NO 61116-28-7. This product is valued for its excellent solubility in non-polar to moderately polar organic solvents, providing consistent and durable coloration. It is primarily used by manufacturers in the plastics, coatings, and specialty ink industries where stable, non-bleeding colorants are required for technical applications.

Application

• Coloration of engineering plastics and thermoplastic resins (e.g., PS, ABS, PC).
• Staining and tinting of industrial coatings, lacquers, and varnishes.
• Manufacture of specialty printing inks, including for security and packaging applications.
• Coloring of waxes, greases, and other hydrocarbon-based products.
• As a colorant for wood stains and leather finishes.
• Potential use in the coloration of synthetic fibers during mass pigmentation.
