Dichromium trioxide

Dichromium trioxide (CAS 1308-38-9) is a high-performance inorganic pigment valued for its exceptional heat stability and chemical resistance across demanding industrial applications. It delivers a durable, opaque green coloration that retains integrity under conditions where organic pigments would degrade. In coatings and industrial paints, it provides permanent green pigmentation for high-temperature finishes, military coatings, and camouflage applications. This material ensures color consistency under thermal stress, which is critical for specialized surface treatments.

Rubber and tire manufacturers incorporate it to achieve stable green coloration in technical rubber compounds without compromising vulcanization chemistry. This ensures the final product maintains its physical properties while achieving the desired aesthetic. Plastics processors use it to pigment engineering polymers that undergo high-temperature extrusion or molding. In these environments, organic alternatives would typically discolor or break down, making this inorganic pigment the preferred choice.

Printing inks for packaging and decorative laminates also rely on it for lightfast, chemically resistant green shades. Its stability ensures that printed materials remain vibrant even when exposed to harsh environmental factors or chemicals. Dichromium trioxide is supplied as a fine, dry powder in technical and pigment grades. Standard specifications include varying particle size distributions and tinting strength classifications to match specific coating, rubber, or plastics processing requirements.

Bulk supply is available in bags and bulk containers, with pigment-grade material typically meeting established industry purity benchmarks. This ensures consistent performance across large-scale manufacturing and industrial chemical applications.
