Description

Solvent Red 49 is a high-performance, oil-soluble azo dye renowned for its vibrant red color and excellent solubility in non-polar organic media. This compound is critical for providing consistent, durable coloration in a wide range of industrial applications where pigment dispersion is not feasible. It is an essential material for manufacturers in the plastics, coatings, and specialty chemical industries seeking reliable and stable colorants for their formulations.

Application

• Primary colorant for coloring hydrocarbon-based fuels, including gasoline and heating oils.
• Solvent dye for plastics and polymer coloration, particularly in polystyrene, acrylics, and polycarbonates.
• Staining agent and colorant in the formulation of printing inks, especially for specialty and security applications.
• Coloring agent for waxes, lubricants, and greases for product identification and branding.
• Used in the manufacture of wood stains and polishes to achieve desired aesthetic finishes.
• Colorant for cosmetic products such as nail polishes and lipsticks where oil solubility is required.
• Staining biological specimens in certain microscopy and laboratory techniques.
