Description

Solvent Green 7 is a synthetic organic dye belonging to the anthraquinone class, known for its excellent solubility in non-polar organic solvents. This property makes it a highly effective and versatile colorant for a wide range of industrial applications where traditional water-soluble dyes are unsuitable. It is primarily utilized by manufacturers in the plastics, coatings, and specialty ink industries to impart a stable and vibrant green color to their products.

Application

• Plastics Coloring: Masterbatch and compound production for coloring polystyrene (PS), polycarbonate (PC), and other engineering plastics.
• Industrial Coatings: Tinting solvent-based paints, lacquers, and wood stains to achieve consistent green hues.
• Specialty Inks: Formulation of flexographic and gravure printing inks for packaging and decorative materials.
• Automotive Styling: Coloring of interior plastic trim components and under-hood parts.
• Wax & Polishes: Addition to colored waxes, shoe polishes, and automotive care products.
• Research & Development: Use as a tracer or marker dye in laboratory and analytical chemistry applications.
