Product Description

Product Introduction

Pigment Red 57:1 is an important monoazo calcium lake organic pigment, commercially known as Lithol Rubine BK, Brilliant Carmine 6B, or Permanent Red 4BP. It features a bright bluish-red shade with high tinting strength and plays a significant role in the printing ink and plastics industries. Its color shade meets the magenta standard for European four-color printing, making it a classic red pigment in the printing ink sector

Key Features

1. High Tinting Strength & Brilliance: Offers extremely high coloring power and a brilliant blue shade red. Only 18-20% pigment concentration is required to achieve 1/1 standard color depth in offset inks.

2. Excellent Flow Properties: Provides good fluidity, stability, and dispersibility in ink systems, effectively improving printing quality and production efficiency.

3. Good Heat Resistance: With heat resistance ranging from 160°C to 260°C, it is suitable for various processing techniques and performs well in flexible PVC and LDPE applications.

4. Environmental Compliance: Meets relevant EU environmental standards (such as aromatic amine and heavy metal content requirements) and is halogen-free. Suitable for sensitive applications including food packaging, cosmetics, and medical products
