Description

Solvent Yellow 2 is a synthetic organic dye belonging to the azo class, identified by CAS NO 60-11-7. This high-purity colorant is valued for its strong, stable yellow hue and excellent solubility in non-polar organic solvents. It is a critical component for manufacturers in the plastics, wax, and hydrocarbon-based industries requiring consistent and vibrant coloration. Our supply ensures reliable performance for demanding technical applications.

Application

• Plastics and Polymer Coloring: Used to impart a bright yellow color to polystyrene, acrylics, and other thermoplastic resins.
• Wax and Candle Manufacturing: Provides stable coloration for paraffin and other waxes used in candles and industrial wax products.
• Fuel and Oil Marking: Serves as a dye for hydrocarbon-based fuels, lubricants, and industrial oils for identification and branding.
• Wood Stains and Polishes: Incorporated into solvent-based formulations for wood stains, varnishes, and polishes.
• Printing Inks: Used in specialty solvent-based inks for flexographic and gravure printing applications.
• Lacquers and Coatings: A colorant for non-aqueous lacquers, metal coatings, and other solvent-borne surface treatments.
