Description

Solvent Yellow 179 is a high-performance, oil-soluble organic dye belonging to the class of solvent dyes. This compound is valued for its excellent solubility in non-polar media, providing strong and stable coloration. It is primarily used in industrial applications where durable, transparent color in hydrophobic systems is required. Key industries that utilize this product include plastics, fuels, and specialty inks.

Application

• Primary coloration of hydrocarbon-based fuels and lubricants for identification and aesthetic purposes.
• Mass coloration of plastics such as polystyrene (PS), polycarbonate (PC), and ABS, offering good heat stability and migration resistance.
• Manufacturing of specialty printing inks, including flexographic and gravure inks for packaging.
• Coloring of waxes, polishes, and wood stains to achieve consistent and vibrant hues.
• As a colorant in solvent-based coatings and lacquers for metal and wood.
• Potential use in the coloration of synthetic fibers during the melt-spinning process.
