Description

Pigment Red 32 is a high-performance, monoazo-based organic pigment renowned for its vibrant red hue and excellent color strength. This pigment is engineered to deliver superior durability and cost-effective coloration for a wide range of industrial applications. It is an essential raw material for manufacturers in the plastics, coatings, and printing ink industries seeking reliable and consistent red shades.

Application

• Plastics Coloring: Widely used for the mass coloration of polyolefins (PP, PE), PVC, and engineering plastics, offering good heat stability and dispersion.
• Industrial Coatings: Imparts durable red color to industrial paints, including air-dry and stoving enamels for machinery, agricultural equipment, and metal finishes.
• Printing Inks: A key component in solvent-based and publication gravure inks, providing strong, opaque red tones for packaging and commercial printing.
• Masterbatch Production: Used as a primary colorant in the manufacture of color concentrates and masterbatches for the plastics industry.
• Synthetic Fibers: Employed in the spin-dyeing process for synthetic fibers to achieve lightfast and wash-fast red colors.
• Rubber Products: Suitable for coloring various rubber goods, where color consistency and stability are required.
