Description

Recolite Fast Red Bl is a high-performance organic pigment belonging to the azo chemical class, identified by CAS No. 39310-30-0. It is valued for its excellent color strength, good lightfastness, and strong tinting properties, making it a critical component for achieving vibrant and durable red hues. This pigment is primarily needed by manufacturers in the plastics, coatings, inks, and synthetic fibers industries seeking reliable and consistent coloration.

Application

• Plastics Coloring: For coloring polyolefins (PP, PE), PVC, polystyrene, and engineering plastics, offering good dispersion and heat stability.
• Industrial Coatings: Used in automotive finishes, industrial maintenance paints, and powder coatings requiring weather resistance.
• Printing Inks: Formulation of solvent-based, water-based, and UV-curable inks for packaging and publication printing.
• Synthetic Fibers: Mass coloration of polyester, nylon, and polyacrylonitrile fibers during the spinning process.
• Masterbatch Production: A key component in the manufacture of color concentrates and additive masterbatches.
• Rubber and Elastomers: Pigmentation of technical rubber goods and consumer elastomeric products.

Quality Control

Our Recolite Fast Red Bl is manufactured under a stringent quality management system. Every batch is tested to ensure consistency in coloristic properties, chemical purity, and physical performance. We provide comprehensive Certificates of Analysis (COA) detailing key parameters such as color strength, hue, particle size distribution, and impurity content, supporting compliance with global industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent moisture absorption, which can affect product performance.
