Description

Solvent Brown 20 is a high-purity, synthetic organic dye belonging to the solvent dye class, identified by CAS NO 61813-86-3. It is valued for its excellent solubility in non-polar to moderately polar organic solvents, providing consistent and vibrant coloration. This product is essential for manufacturers in the plastics, coatings, and specialty ink industries seeking reliable, non-aqueous colorants for their formulations.

Application

• Primary coloring agent for thermoplastics such as polystyrene, ABS, and polycarbonate.
• Solvent-based industrial coatings and wood stains requiring deep, transparent brown shades.
• Manufacturing of specialty printing inks, including flexographic and gravure inks.
• Coloration of waxes, polishes, and lubricants.
• Tinting of fuels and hydrocarbon-based fluids for identification purposes.
• Coloring agent for synthetic fibers during mass coloration (dope dyeing).
