Description

Chloramine Yellow CAS NO 14500-83-5 is a synthetic organic pigment belonging to the diarylide yellow class, known for its bright, greenish-yellow hue and excellent color strength. This high-performance pigment is valued for its good lightfastness, heat stability, and resistance to solvents, making it a critical component in demanding coloration applications. It is primarily sought after by manufacturers in the plastics, inks, coatings, and synthetic fiber industries for producing durable and vibrant yellow shades.

Application

• Plastics Coloring: Masterbatch and compound production for polyethylene (PE), polypropylene (PP), polystyrene (PS), and PVC, offering good dispersion and thermal stability during processing.
• Printing Inks: Formulation of high-quality offset, gravure, and flexographic inks for packaging and publications, providing strong tinctorial strength and print clarity.
• Industrial Coatings: Used in solvent-based and coil coatings for automotive, industrial equipment, and architectural applications where weather resistance is required.
• Synthetic Fibers: Mass coloration (dope dyeing) of polyamide, polyester, and polyacrylonitrile fibers to achieve lightfast and wash-fast yellow colors.
• Rubber and Elastomers: Coloring of technical rubber goods, footwear, and other elastomeric products.
• Artist Colors: A component in the manufacture of professional-grade oil and acrylic paints.
