Description

C.I. Solvent Black 43 is a high-performance, oil-soluble black dye belonging to the solvent dye classification. This product is valued for its excellent solubility in non-polar organic media and its ability to impart deep, intense black coloration. It is primarily used in industrial applications where permanent, non-migrating color is required for hydrophobic substrates. The compound is identified by CAS NO 69458-41-9.

Application

• Primary coloring agent for plastics and polymers, including polystyrene, ABS, and polycarbonate.
• Pigmentation of printing inks, especially for specialty and industrial marking applications.
• Dyeing of hydrocarbon-based fuels and lubricants for identification and branding purposes.
• Coloration of waxes, greases, and polishes to achieve uniform black finishes.
• Staining and tinting of wood stains and coatings for decorative and protective layers.
• Manufacture of toners and colorants for specialty chemical formulations.
