Description

Solvent Blue 70 is a high-performance, oil-soluble anthraquinone dye known for its excellent solubility and stability in non-polar media. This product is engineered to deliver consistent, vibrant blue coloration and superior performance in demanding industrial applications. It is a critical component for manufacturers in the plastics, ink, and specialty coatings sectors who require reliable, heat-stable colorants for their formulations.

Application

• Primary colorant for the mass coloration of polystyrene (PS), polycarbonate (PC), and other engineering plastics.
• Manufacturing of high-quality printing inks, including solvent-based and oil-based systems for packaging and publications.
• Pigmentation of industrial coatings, lacquers, and wood stains where transparency and lightfastness are required.
• Coloring of synthetic fibers during the melt-spinning process.
• Production of colored waxes, greases, and lubricants for identification and branding purposes.
• Used in the formulation of specialty ballpoint pen inks and marker pens.
• Tinting agent for fuel and oil markers for tax identification and leak detection.
