Description

Solvent Green 28 is a high-performance, light-sensitive organic dye belonging to the solvent dye class, identified by CAS No. 71839-01-5. It is valued for its excellent solubility in non-polar to moderately polar organic solvents, providing vibrant and stable coloration. This product is essential for industries requiring durable, transparent tints for plastics, resins, and specialty coatings, where color consistency and performance under processing conditions are critical.

Application

• Plastics and Polymer Coloring: Primary application for tinting polystyrene (PS), acrylics (PMMA), polycarbonate (PC), and other engineering plastics.
• Industrial Coatings and Inks: Used in solvent-based lacquers, wood stains, and specialty printing inks to achieve transparent, lightfast colors.
• Automotive and Decorative Finishes: Imparts color to clear coats, vinyl films, and other decorative layers requiring high transparency.
• Fuel and Oil Markers: Suitable for non-aqueous systems like hydrocarbon-based fuels and lubricants for identification purposes.
• Wax and Grease Coloring: Effective for coloring candles, polishes, and industrial greases.
• Specialty Chemical Formulations: Used in research and development for creating colored masterbatches and custom color matches.
