Description

Solvent Black 27 is a high-performance, solvent-soluble black dye belonging to the anthraquinone class. This product is valued for its excellent solubility in a wide range of organic solvents, providing deep, intense coloration with strong light and chemical fastness properties. It is primarily used in industrial applications where durable, non-aqueous coloration is required, such as in the coloring of plastics, synthetic fibers, inks, and specialty coatings. Our supply ensures consistent quality and reliable performance for demanding technical applications.

Application

• Primary coloring agent for plastics and synthetic resins (e.g., polystyrene, ABS, polycarbonate).
• Manufacturing of high-quality printing inks, including specialty inks for non-porous surfaces.
• Dyeing of synthetic fibers and technical textiles where solvent-based processes are employed.
• Coloration of wood stains, lacquers, and industrial coatings.
• Production of colored waxes and polishes.
• Used in the formulation of ballpoint pen inks and other writing instruments.
• As a colorant for gasoline and fuel oils for identification purposes.
• Potential use in the coloration of specialty rubber and elastomer products.
