Description

Solvent Blue 59 is a high-performance anthraquinone-based dye known for its excellent solubility in organic solvents and strong, stable blue coloration. This product is essential for industries requiring vibrant, non-polar colorants that offer superior light and chemical fastness. It is primarily used by manufacturers in the plastics, ink, and specialty coatings sectors to achieve consistent and durable blue shades in their formulations.

Application

• Primary colorant for polystyrene (PS), polycarbonate (PC), and other engineering plastics.
• Solvent-based printing inks for packaging and publications.
• Coloration of industrial coatings, wood stains, and automotive finishes.
• Dyeing of synthetic fibers and specialty textiles.
• Manufacturing of colored waxes, polishes, and lubricants for visual identification.
• Pigment for ballpoint pen inks and marker fluids.
• Color concentrate masterbatch production for the plastics industry.
