Description

C.I. Solvent Blue 83 is a high-performance, oil-soluble anthraquinone dye widely recognized for its excellent solubility and strong, clean blue shade. This product is valued for its superior color strength, thermal stability, and lightfastness, making it a critical component for demanding coloration applications. It is primarily used by manufacturers in the plastics, synthetic fibers, and specialty ink industries seeking consistent, high-quality pigmentation.

Application

• Primary coloration of engineering plastics and polymers, including polystyrene (PS), polycarbonate (PC), and ABS.
• Mass coloration (spinning dope dyeing) of synthetic fibers such as polyester and acetate to achieve uniform, deep shades.
• Manufacturing of high-quality solvent-based inks for specialty printing and security applications.
• Coloring of waxes, lubricants, and other non-polar hydrocarbon-based products.
• Pigmentation of specialty coatings and lacquers requiring excellent solubility and stability.
• Used as a colorant for gasoline and other fuels for identification purposes.
