Description

Solvent Red 3 is a synthetic organic dye belonging to the azo class, widely recognized for its vibrant red color and excellent solubility in non-polar media. This compound is valued for its strong tinting strength and stability in various organic matrices, making it a critical component for coloration in industrial applications. It is primarily utilized by manufacturers in the plastics, inks, coatings, and specialty chemical sectors where precise and durable coloration is required.

Application

• Plastics Coloring: Used as a colorant for polystyrene, ABS, polycarbonate, and other engineering plastics.
• Ink Formulation: Imparts a bright red hue in solvent-based printing inks for packaging and publications.
• Industrial Coatings: Employed in lacquers, wood stains, and automotive finishes requiring high color fastness.
• Waxes & Polishes: Adds color to candles, shoe polishes, and floor waxes.
• Oil & Fuel Marking: Acts as a dye for marking lubricants, heating oils, and other hydrocarbon-based fluids.
• Specialty Chemicals: Serves as a colorant in adhesives, sealants, and cleaning products.
