Description

Solvent Yellow 160:1 is a high-performance, oil-soluble monoazo dye widely used for its excellent tinctorial strength and stability. This pigment is valued for its ability to impart a clean, bright yellow hue to a variety of non-polar substrates. It is an essential coloring agent for industries requiring durable and consistent coloration in plastics, synthetic fibers, and specialty inks. The compound is supplied under the CAS registry number 94945-27-4.

Application

• Plastics Coloring: Primary application for coloring polystyrene (PS), ABS, polycarbonate (PC), and other engineering plastics.
• Synthetic Fibers: Mass coloration of polyester, nylon, and polypropylene fibers during the melt-spinning process.
• Industrial Inks: Formulation of solvent-based and oil-based printing inks for packaging and publications.
• Waxes & Greases: Coloring of paraffin waxes, candles, and industrial lubricating greases.
• Wood Stains & Coatings: Used in transparent and opaque wood stains and industrial wood coatings.
• Masterbatch Production: Manufacture of high-concentration color masterbatches for thermoplastics.
