Description

Solvent Orange 56 is a high-performance, oil-soluble azo dye renowned for its vibrant orange hue and excellent solubility in non-polar media. This product is engineered to deliver consistent color strength and superior lightfastness, making it a critical component for achieving precise and durable coloration. It is primarily utilized by manufacturers in the plastics, wax, and hydrocarbon-based solvent industries for coloring a wide range of products, from synthetic fibers and masterbatches to specialty inks and coatings.

Application

• Primary coloration of polyolefins (e.g., polyethylene, polypropylene) for fibers, films, and molded articles.
• Manufacturing of color concentrates and masterbatches for the plastics industry.
• Coloring of hydrocarbon-based solvents, fuels, and lubricants for identification purposes.
• Imparting color to waxes, including candles, crayons, and polishes.
• Used in the formulation of oil-based inks and specialty printing inks.
• Coloration of synthetic resins and adhesives.
• Staining and marking applications in industrial and laboratory settings.
• Potential use in the coloration of wood stains and varnishes.
