Description

Solvent Yellow 12 is a synthetic organic dye belonging to the azo class, widely recognized for its bright, clean yellow hue. This high-performance colorant is valued for its excellent solubility in non-polar organic solvents and its strong tinting strength, making it a cost-effective choice for demanding industrial applications. It is primarily utilized by manufacturers in the plastics, printing ink, and coatings industries seeking stable and vibrant coloration.

Application

• Primary colorant for plastics such as polystyrene, ABS, and polycarbonate.
• Manufacturing of printing inks, especially for packaging and publication gravure inks.
• Coloration of industrial coatings and lacquers for metals and wood.
• Dyeing of hydrocarbon-based fuels and lubricants for identification purposes.
• Tinting of waxes and polishes.
• Coloring for specialty solvents and chemical formulations.
