Description

Solvent Black 5 is a high-performance, oil-soluble diazo dye widely recognized for its intense black coloration and excellent solubility in non-polar organic media. This product is essential for industries requiring deep, permanent black shades with superior light and chemical fastness properties. Key users include manufacturers of plastics, inks, waxes, and specialty coatings, where consistent color strength and stability are critical for product quality.

Application

• Plastics and Polymers: A primary colorant for mass coloration of polystyrene, ABS, polycarbonate, and other engineering plastics.
• Printing Inks: Used in solvent-based inks for flexographic, gravure, and specialty printing applications, providing deep black tones.
• Waxes and Polishes: Imparts a rich black color to shoe polishes, automotive waxes, and industrial buffing compounds.
• Wood Stains and Coatings: Employed in solvent-borne wood stains and lacquers to achieve dark woodgrain effects.
• Fuel and Oil Marking: Acts as a dye for industrial fuel oils, lubricants, and other hydrocarbon-based fluids for identification.
• Specialty Coatings: Suitable for coloring synthetic resins and coatings where compatibility with organic solvents is required.
