Description

Solvent Yellow 93 is a high-performance, oil-soluble azo dye known for its excellent tinctorial strength and stability. This product is valued for its ability to impart a clean, bright yellow hue with superior lightfastness and heat resistance in non-polar environments. It is primarily utilized by manufacturers in the plastics, printing inks, and industrial coatings sectors seeking consistent and durable coloration.

Application

• Coloration of thermoplastics such as polystyrene, ABS, and polycarbonate.
• Manufacturing of printing inks, including flexographic and gravure inks for packaging.
• Pigmentation of industrial coatings and solvent-based paints.
• Coloring of waxes, greases, and various lubricants.
• Tinting of specialty oils and fuel markers for identification purposes.
• Used in the coloration of certain wood stains and transparent finishes.
