Description

Pigment Red 52:2 is a high-performance, calcium-based monoazo lake pigment known for its excellent color strength and durability. This pigment is valued for its ability to provide a clean, bluish-red shade with strong tinting power and good solvent resistance, making it a critical component in demanding industrial applications. It is primarily sought after by manufacturers in the plastics, coatings, and printing ink industries who require consistent, high-quality coloration for their products.

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 shades in air-drying and baking finishes, including automotive refinishes and industrial maintenance paints.
• Printing Inks: A key pigment for offset, gravure, and flexographic inks, providing strong, transparent red tones for packaging and publications.
• Masterbatch Production: An essential component for creating high-concentration color masterbatches used in plastic processing.
• Synthetic Fibers: Employed in the spin-dyeing of fibers where colorfastness is required.
• Rubber and Elastomers: Used to color various rubber products, benefiting from its chemical resistance.
