Description

n-(2-Ethylhexyl)-1-[[3-Methyl-4-[(2-Methylphenyl)Azo]Phenyl]Azo]Naphthalen-2-Amine is a high-performance, oil-soluble monoazo dye belonging to the Solvent Yellow class. This compound is valued for its strong tinctorial strength and excellent solubility in non-polar organic media, providing vibrant and stable coloration. It is primarily utilized in industrial applications where durable, lightfast, and heat-resistant pigmentation is required for hydrophobic materials.

Application

• Solvent Dyes: Primary use as a coloring agent for hydrocarbon-based solvents, fuels, lubricants, and waxes.
• Plastics and Polymers: Mass coloration of olefinic polymers (e.g., polyethylene, polypropylene), polystyrene, and other engineering plastics.
• Printing Inks: Formulation of specialty inks for non-porous substrates, including metal decoration and plastic film printing.
• Wood Stains and Coatings: Imparting transparent, penetrating color to wood stains, lacquers, and industrial coatings.
• Automotive and Industrial Fluids: Color-coding of hydraulic fluids, transmission oils, greases, and antifreeze for leak detection and product identification.
• Personal Care: Coloring agent for cosmetic products like lipsticks and nail polishes where oil solubility is essential (subject to regional regulatory approval).
