Description

Blue 9 CAS NO 1342-65-0 is a high-purity synthetic ultramarine blue pigment, chemically classified as a complex sodium aluminum sulfosilicate. This inorganic pigment is valued for its exceptional color stability, non-toxic nature, and excellent heat and light resistance, making it a superior alternative to organic blues. It is an essential raw material for manufacturers seeking vibrant, durable, and safe coloration across a wide range of industrial and consumer products.

Application

• Plastics and Masterbatch: Provides stable, heat-resistant blue coloration for polyethylene, polypropylene, PVC, and engineering plastics.
• Coatings and Paints: Used in industrial, decorative, and powder coatings for its excellent weatherability and chemical inertness.
• Printing Inks: A key pigment for high-quality packaging, publication, and security inks requiring color consistency.
• Cosmetics and Personal Care: Approved for use in eye area cosmetics (e.g., eyeshadow, eyeliner) and other color cosmetics as a safe, mineral-based colorant.
• Artists' Colors: A premium pigment for high-grade oil paints, acrylics, watercolors, and pastels, prized for its permanence.
• Construction Materials: Imparts long-lasting color to concrete, mortar, roofing granules, and other building materials.
• Paper and Specialty Coatings: Used in colored paper production and functional coatings where non-toxicity is critical.
• Food Contact Materials: Suitable for coloring plastics and coatings intended for food packaging applications, subject to regional compliance.
