Description

Solvent Yellow 90 is a high-purity, light-stable organic dye belonging to the solvent dye class, identified by CAS No. 61116-26-5. It is valued for its excellent solubility in non-polar to moderately polar organic solvents, providing strong, vivid coloration. This product is essential for industrial applications requiring durable and consistent yellow pigmentation in various polymer and hydrocarbon-based systems.

Application

• Plastics and Polymer Coloring: Primary application for coloring polystyrene (PS), polycarbonate (PC), ABS, and other engineering plastics.
• Hydrocarbon-Based Inks and Coatings: Used in flexographic, gravure, and specialty printing inks for packaging and publications.
• Fuel and Oil Marking: Acts as a colorant for gasoline, diesel, lubricating oils, and greases for identification and branding.
• Wax and Candle Coloring: Provides stable and vibrant yellow color in paraffin and other wax formulations.
• Wood Stains and Polishes: Imparts transparent, penetrating color in solvent-borne wood treatment products.
• Personal Care Products: Used in the formulation of hair sprays, nail polishes, and other cosmetic products where solubility is key.
