Description

1-[(4-Chloro-2-Nitrophenyl)Azo]-2-Naphthol CAS NO 6410-13-5 is a synthetic organic azo compound, specifically a diazo pigment, known for its vibrant color properties. This chemical is valued for its excellent tinting strength and stability, making it a critical component in high-performance colorant systems. It is primarily required by manufacturers in the pigments and dyes industry for producing durable and consistent colors in plastics, inks, and specialty coatings.

Application

• Pigment for Plastics: Used as a colorant in the mass coloration of various polymers, including PVC, polyolefins, and engineering plastics, offering good heat and light stability.
• Printing Inks: Imparts strong, vivid shades in solvent-based, water-based, and UV-curable inks for packaging, publication, and specialty printing.
• Industrial Coatings: Provides coloration for industrial paints, automotive refinishes, and powder coatings where color fastness is essential.
• Synthetic Fibers: Employed in the spin-dyeing process for synthetic fibers like polyester and nylon to achieve uniform and wash-fast colors.
• Masterbatch Production: A key ingredient in color masterbatches and concentrates for simplified and precise coloring of plastics.
• Lacquers and Varnishes: Used in transparent and opaque lacquers to provide decorative and protective colored finishes.
