Description

Solvent Red 100 is a high-purity, oil-soluble azo dye renowned for its intense and stable red coloration. This compound is critical for achieving consistent, vibrant hues in non-aqueous systems where color fastness and solubility are paramount. It is an essential component for manufacturers in the plastics, printing ink, and specialty coatings industries seeking reliable pigmentation.

Application

• Primary colorant for solvent-based printing inks, including flexographic and gravure inks.
• Pigmentation of engineering plastics (e.g., polystyrene, ABS) and synthetic fibers.
• Staining and coloring of wood finishes, lacquers, and varnishes.
• Manufacture of colored waxes and polishes.
• Colorant for specialty oils and greases.
• Production of ballpoint pen inks and other writing instruments.
• Used in the coloration of certain cosmetic formulations where oil solubility is required.
