Description

Spinels, Aluminum Chromium Cobalt Zinc Blue is a high-performance, inorganic mixed metal oxide pigment. This compound is valued for its exceptional thermal stability, chemical inertness, and vibrant blue color, making it a superior alternative to organic pigments and less stable inorganic options. It is primarily used by manufacturers in the ceramics, plastics, coatings, and specialty glass industries where durability and color consistency under harsh conditions are critical.

Application

• Ceramic Glazes and Bodies: Imparts stable blue coloration in sanitaryware, tiles, and artistic ceramics fired at high temperatures.
• Engineering Plastics and Masterbatches: Provides heat-stable and UV-resistant coloring for automotive components, appliances, and industrial polymers.
• High-Temperature Paints and Coatings: Used in industrial coatings, coil coatings, and powder coatings requiring weatherability and chemical resistance.
• Specialty Glass and Enamels: Acts as a colorant in borosilicate glass, architectural glass, and porcelain enamels.
• Construction Materials: Colors concrete, roofing granules, and other cementitious products for long-lasting aesthetic appeal.
• Artists' Colors and Inks: Employed in high-quality artists' paints and specialty printing inks for its permanence and brilliance.
