Description

Solvent Red 146 is a high-performance, oil-soluble synthetic dye belonging to the azo class. This compound is valued for its excellent solubility in non-polar organic media and its ability to impart a strong, vivid red coloration. It is primarily utilized in industrial applications where durable, non-bleeding color is required in hydrophobic systems. Key industries that rely on this pigment include plastics, inks, and specialty coatings.

Application

• Primary coloring agent for plastics and polymers, including polystyrene, ABS, and polycarbonate.
• Manufacture of printing inks, particularly for specialty and industrial applications requiring oil solubility.
• Coloration of solvent-based coatings, lacquers, and wood stains.
• Production of colored waxes and greases.
• Tinting agent for fuels and lubricants for identification purposes.
• Coloring for artists' oil paints and related artistic materials.
