Description

Dilead Chromate Oxide CAS NO 18454-12-1 is an inorganic compound consisting of lead, chromium, and oxygen, known for its distinctive orange-red color and pigment properties. This compound is valued for its high opacity, excellent lightfastness, and chemical stability in specific formulations. It is primarily sought by manufacturers in the pigments, coatings, ceramics, and plastics industries for applications requiring durable and vibrant coloration.

Application

• Industrial Pigments: Used as a colorant in the production of paints, primers, and industrial coatings for metals and wood.
• Plastics and Polymers: Imparts color to PVC, polyolefins, and other engineering plastics for automotive parts, consumer goods, and construction materials.
• Ceramic Glazes and Enamels: Provides stable coloration in ceramic frits, glazes, and porcelain enamels applied to tiles and sanitaryware.
• Printing Inks: Serves as a pigment in specialty printing inks where chemical resistance is required.
• Artists' Colors: A component in the formulation of certain high-performance artists' paints and pastels.
• Rust-Inhibitive Primers: Historically used in corrosion-resistant primer formulations for steel structures (subject to regional regulatory compliance).
