Description

Solvent Green 3 is a synthetic organic dye belonging to the anthraquinone chemical class, widely recognized for its vibrant green hue. This high-performance colorant is valued for its excellent solubility in non-polar organic solvents and its stability under typical processing conditions. It serves as a critical component for industrial manufacturers requiring consistent and durable coloration in plastics, inks, and specialty coatings. The compound is identified by CAS No. 128-80-3.

Application

Solvent Green 3 is a versatile colorant used across multiple industries where non-aqueous coloration is required. Its primary applications include:

• Plastics and Polymers: Coloring of polystyrene, acrylics, polycarbonate, and other engineering plastics for consumer goods, automotive parts, and electronic housings.
• Printing Inks: Formulation of solvent-based inks for flexographic, gravure, and specialty printing applications, offering good lightfastness.
• Industrial Coatings and Paints: Used in lacquers, wood stains, and metal coatings where solubility in organic solvents is essential.
• Waxes and Polishes: Imparting color to automotive waxes, shoe polishes, and other solvent-based maintenance products.
• Fuel and Oil Markers: Potential use as a dye for marking or identifying specific grades of fuels and lubricants.
• Research & Development: Employed as a chemical intermediate or a staining agent in laboratory and analytical settings.
