Description

Pigment Red 49:2 is a high-performance, calcium-based salt of a monoazo pigment, valued for its excellent color strength and durability. This pigment is engineered to provide a bright, clean red shade with superior lightfastness and chemical resistance, making it a critical component for demanding industrial applications. It is primarily used by manufacturers in the coatings, plastics, and printing ink industries seeking reliable and consistent coloration.

Application

• Industrial Coatings: Used in automotive primers, industrial maintenance paints, and coil coatings for its weather resistance and opacity.
• Plastics Coloring: Imparts a stable red color to PVC, polyolefins, and other engineering plastics, suitable for outdoor applications.
• Printing Inks: A key pigment for offset, flexographic, and gravure inks, especially for packaging where color consistency is vital.
• Masterbatch Production: Employed as a high-strength colorant in pigment concentrates for efficient dispersion in polymer processing.
• Textile Printing: Used in pigment printing pastes for fabrics, offering good washfastness.
• Specialty Applications: Suitable for coloring construction materials, artists' colors, and other specialty products requiring a durable red pigment.
