Description

Solvent Blue 35 is a high-performance anthraquinone-based solvent dye known for its excellent solubility in organic media and strong, vibrant blue coloration. This product is engineered to deliver consistent color strength and superior fastness properties, making it a critical component for demanding industrial applications. It is primarily used by manufacturers in the plastics, ink, and specialty coatings industries who require reliable, non-polar colorants for their formulations.

Application

• Plastics Coloring: A primary colorant for mass coloration of various polymers, including polystyrene (PS), polycarbonate (PC), and ABS, providing excellent heat stability and migration resistance.
• Ink Formulations: Used in specialty printing inks, particularly for non-polar systems like flexographic and gravure inks, offering brilliant shade and good lightfastness.
• Industrial Coatings: Imparts color to solvent-based coatings, lacquers, and wood stains where compatibility with organic solvents is paramount.
• Waxes & Polishes: Employed in the coloration of candles, wax polishes, and other hydrocarbon-based products.
• Fuel & Marker Dyes: Suitable for use as a identifying dye in hydrocarbon fuels and industrial fluids.
• Specialty Resins: Used to color unsaturated polyester resins and other liquid polymer systems.
