Description

Solvent Yellow 13 is a high-performance, oil-soluble azo dye widely recognized for its strong, clean yellow hue and excellent solubility in non-polar media. This product is essential for industrial applications requiring durable, non-bleeding coloration in hydrophobic systems. It is primarily utilized by manufacturers in the plastics, printing ink, and specialty coatings industries seeking consistent and reliable colorants.

Application

• Primary colorant for the mass coloration of olefin polymers, including polypropylene (PP) and polyethylene (PE).
• Formulation of high-quality printing inks, especially for packaging and publication gravure.
• Coloration of industrial coatings, lacquers, and wood stains.
• Dyeing of hydrocarbon-based solvents, waxes, and lubricants for identification purposes.
• Manufacturing of colored masterbatches and concentrates for the plastics industry.
• Used in the coloration of certain candles and polishes.
