Description

C.I. Disperse Yellow 108 is a high-performance, monoazo-based synthetic dye belonging to the disperse dye class, widely recognized for its bright and stable yellow hue. Its primary value lies in its excellent sublimation fastness and wash fastness, making it ideal for demanding coloration processes on synthetic fibers. This product is essential for manufacturers in the textile and polymer industries seeking reliable and consistent coloration for polyester, acetate, and nylon materials.

Application

• Primary dyeing and printing of polyester fibers and fabrics.
• Coloration of acetate and triacetate textiles.
• Mass coloration (dope dyeing) of nylon and other synthetic polymers during melt spinning.
• Production of colored plastic masterbatches for films, filaments, and molded articles.
• Used in the manufacture of transfer papers for sublimation printing applications.
• Potential use as a colorant for specific inks and coatings formulated for synthetic substrates.
