Description

Solvent Yellow 93 is a high-performance, oil-soluble dye belonging to the diarylide chemical class. This compound is valued for its strong tinctorial strength, excellent solubility in non-polar media, and good thermal stability, making it a reliable colorant for demanding industrial applications. It is primarily used by manufacturers in the plastics, coatings, and specialty ink industries to impart a clean, vibrant yellow hue to their products.

Application

• Plastics Coloring: For coloring a wide range of polymers, including polyethylene (PE), polypropylene (PP), polystyrene (PS), and ABS, offering good dispersion and heat resistance during processing.
• Industrial Coatings and Paints: As a pigment for solvent-based industrial coatings, automotive refinishes, and decorative paints, providing durability and weatherability.
• Printing Inks: Used in specialty printing inks, including flexographic and gravure inks, for packaging and publications.
• Waxes and Greases: For coloring petroleum-based products, candles, and industrial lubricants.
• Wood Stains and Varnishes: To achieve consistent yellow tones in wood treatment products.
• Masterbatch Production: As a key component in the manufacture of color concentrates for the plastics industry.
