Description

Solvent Blue 4 is a synthetic anthraquinone dye known for its vibrant blue color and excellent solubility in organic solvents. This high-purity colorant is essential for providing consistent, non-polar coloration in a variety of industrial applications. It is primarily used by manufacturers in the plastics, ink, and specialty coatings industries seeking reliable and stable blue hues for their products.

Application

• Primary colorant for polystyrene (PS), polycarbonate (PC), and other engineering plastics.
• Solvent-based printing inks for packaging and publications.
• Coloration of lubricating oils, greases, and fuels for identification purposes.
• Staining agent for microscopy and biological applications in non-aqueous systems.
• Manufacturing of wood stains and polishes.
• Coloring for waxes and candles.
• Pigment for specialty coatings and lacquers.
