Description

Solvent Red 26 is a synthetic organic colorant belonging to the azo dye class, valued for its strong, stable red hue in non-aqueous systems. Its primary commercial value lies in its excellent solubility in organic solvents and oils, providing vibrant, durable coloration. This pigment is essential for manufacturers in the plastics, printing inks, and coatings industries seeking consistent, high-performance colorants for their formulations.

Application

• Plastics Coloring: Used for mass coloration of various polymers, including polystyrene, ABS, and polycarbonate, offering good heat stability and dispersion.
• Industrial Printing Inks: A key component in solvent-based inks for flexographic and gravure printing on films, foils, and other non-porous substrates.
• Coatings and Paints: Imparts color to industrial lacquers, wood stains, and automotive refinish paints where solvent compatibility is required.
• Waxes and Polishes: Employed to color shoe polishes, floor waxes, and other solvent-based maintenance products.
• Office Supplies: Used in the manufacture of colored pencils, stamp pad inks, and other stationery items.
• Specialty Fluids: Suitable for coloring lubricating greases and other functional fluids for identification purposes.
