Description

Pigment Red 52:2 is a high-performance, calcium-based monoazo lake pigment renowned for its clean, bluish-red shade and excellent durability. This pigment is engineered to deliver superior color strength, lightfastness, and heat stability, making it a critical component for achieving consistent, high-quality coloration. It is primarily utilized by manufacturers in the plastics, coatings, and printing ink industries who require reliable and vibrant red hues for demanding applications.

Application

• Plastics Coloring: For coloring polyolefins (PP, PE), PVC, and engineering plastics, offering good dispersion and heat stability during processing.
• Industrial Coatings: Imparts durable and weather-resistant red colors in automotive refinish, industrial maintenance, and decorative paint systems.
• Printing Inks: Used in solvent-based, water-based, and publication gravure inks for packaging and commercial printing due to its color intensity and printability.
• Masterbatch Production: A key colorant for creating concentrated pigment preparations used in bulk plastic manufacturing.
• Synthetic Fibers: Employed in the mass coloration of fibers where consistent shade and fastness properties are required.
• Specialty Applications: Suitable for colored pencils, artists' materials, and other applications demanding a bright red pigment.
