Description

Pigment Red 57:1 is a high-performance, calcium-based monoazo pigment renowned for its vibrant, bluish-red shade and excellent cost-performance ratio. This pigment is a critical component for achieving consistent, durable, and economical coloration across a wide range of industrial applications. It is essential for manufacturers in the printing, plastics, and coatings industries seeking reliable colorants for mass-produced goods. The compound is supplied as a fine powder, optimized for ease of dispersion and integration into various media.

Application

• Printing Inks: The primary application, especially for high-volume offset, flexographic, and gravure printing inks, providing the standard magenta for process color (CMYK) printing.
• Plastics Coloring: Used for the mass coloration of polyolefins (PP, PE), PVC, and other polymers where good heat stability and color strength are required.
• Industrial Coatings: Imparts color to decorative and protective coatings for consumer products, toys, and general industrial finishes.
• Paper Coatings: Employed in the surface coloring and coating of paper and board for packaging and publications.
• Textile Printing: Utilized in certain pigment printing pastes for textiles, offering good wash fastness.
• Specialty Applications: Suitable for use in colored pencils, chalks, and other artist materials, as well as in the coloration of rubber and leather.
