Description

Solvent Black 5 is a high-performance, solvent-soluble black dye belonging to the azo dye class, widely recognized for its excellent tinctorial strength and stability. This product is essential for achieving deep, consistent black coloration in a variety of non-aqueous systems where water-based dyes are unsuitable. It is a critical raw material for manufacturers in the printing inks, plastics, and specialty coatings industries who require reliable and vibrant pigmentation.

Application

• Printing Inks: A primary colorant for solvent-based flexographic, gravure, and specialty printing inks, particularly for films and foils.
• Plastics Coloring: Used for mass coloration of various polymers, including polystyrene, ABS, and polycarbonate, providing good heat stability and dispersion.
• Wood Stains and Finishes: Imparts rich, penetrating color in solvent-borne wood stains and lacquers for furniture and decorative applications.
• Industrial Coatings: Employed in automotive refinish paints, aerosol sprays, and other industrial coatings requiring solvent solubility.
• Waxes and Polishes: Colors solvent-based shoe polishes, automotive waxes, and floor polishes.
• Ballpoint Pen Inks: A key component in the formulation of oil-based ballpoint pen inks.
• Specialty Markers and Stamping Pads: Provides intense color for permanent markers and ink pads.
