Description

Solvent Green 5 is a synthetic organic dye belonging to the anthraquinone chemical class, recognized for its stable and vivid green coloration. This high-purity colorant is valued for its excellent solubility in non-polar organic solvents and its strong tinting strength, making it a critical component in specialized industrial formulations. It is primarily sought by manufacturers in the plastics, coatings, and specialty ink industries requiring consistent, non-migratory color for technical applications.

Application

• Plastics Coloring: Used as a colorant for engineering plastics, polystyrene, ABS, and other polymers where high-temperature stability is required.
• Industrial Coatings & Paints: Imparts durable green color to solvent-based industrial coatings, automotive finishes, and decorative paints.
• Specialty Inks: A key pigment for printing inks, including those used in security printing and packaging.
• Wood Stains & Polishes: Provides transparent, penetrating color in solvent-based wood treatment products.
• Lacquers and Varnishes: Used to color clear lacquers and protective coatings for metals and wood.
• Fuel & Oil Markers: Employed as a dye for marking fuels, lubricants, and other petroleum-derived products.
