Description

Chromium Lead Oxide Sulfate, Silica-Modified is an advanced inorganic pigment and functional additive engineered for high-performance applications. This silica-modified compound offers enhanced stability, dispersion, and color properties compared to traditional lead chromate pigments. It is primarily utilized in industries requiring durable, light-fast, and chemically resistant coloration, such as specialized coatings, plastics, and ceramics. Our product ensures consistent quality and reliable supply for demanding industrial formulations.

Application

• High-Performance Industrial Coatings: Used in primers, anti-corrosive paints, and marine coatings where exceptional durability and chemical resistance are required.
• Plastics and Masterbatch Coloring: Provides vibrant, heat-stable coloration for engineering plastics, PVC, and synthetic fibers.
• Ceramic Glazes and Pigments: Imparts stable yellow-to-orange hues in ceramic tiles, sanitaryware, and specialty glass.
• Specialty Inks: Employed in security printing and other specialty ink applications demanding high opacity and weatherability.
• Stabilizer and Functional Filler: The silica modification can contribute to improved UV stability and mechanical properties in composite materials.
