General data

Chrome Oxide Green (Cr2O3) is a highly stable, opaque, and lightfast green inorganic pigment known for its exceptional heat resistance and durability, making it ideal for paints, construction materials, plastics, and ceramic glazes. It is used in applications requiring high chemical resistance, such as industrial coatings, rubber, and refractory bricks.

Key Aspects and Properties:

• Composition: An inorganic compound, specifically chromium(III) oxide.
• Appearance: A dull, olive-green powder.
• Properties: Excellent lightfastness, highly weather stable, heat-resistant, and chemically inert.
• Safety: Generally non-toxic, but, like any pigment, inhaling the dust should be avoided.
  Stability: Very low chromium(VI) content in modern pigments.
• Key Uses:
• Construction & Building Materials: Used extensively to color concrete, mortar, roof tiles, and paving stones due to its stability against UV light and weathering.
• Paints & Coatings: Ideal for exterior paints, automotive coatings, and camouflage coatings.
• Ceramics & Glass: Used to create green glazes, stains, and for coloring glass.
• Plastics & Rubber: Acts as a colorant in polymers and rubber articles.
• Industrial & Technical: Used in refractory bricks for high-temperature applications (glass and fiberglass), stainless steel electrodes, and as an abrasive in polishing compounds.
• Arts: A reliable, opaque pigment for oil, acrylic, and water color paints.
