Description

Solvent Green 28 is a high-performance, oil-soluble green dye belonging to the anthraquinone chemical class. This product is valued for its excellent color strength, stability, and solubility in non-polar organic media, making it a critical component for precise coloration. It is primarily required by manufacturers in the plastics, coatings, and specialty ink industries seeking consistent and durable green hues. The compound is supplied under strict quality control to ensure batch-to-batch uniformity for demanding industrial applications.

Application

• Plastics Coloring: Masterbatch and compound production for polyethylene (PE), polypropylene (PP), polystyrene (PS), and ABS resins.
• Industrial Coatings & Paints: Solvent-based coatings, automotive refinish paints, and industrial maintenance paints requiring lightfastness.
• Specialty Inks: Formulation of printing inks for plastics, metal decoration, and other applications where solvent resistance is key.
• Wood Stains & Polishes: Providing transparent, penetrating color in oil-based wood treatment products.
• Waxes & Greases: Identification and coloration of lubricants, petroleum products, and candle wax.
• Cosmetic & Personal Care: Used in limited, specific applications for non-aqueous cosmetic formulations where approved.
