Green Pigments for Building Materials
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
Global Supplier of Durable Green Oxides
Deqing Demi Pigment Technology Co., Ltd. provides the highest grade of Chromium Oxide Green for the construction industry. Our green pigments are manufactured using a high-temperature calcination process, resulting in a pigment that is physically and chemically indestructible in normal environmental conditions. We support manufacturers of green-colored infrastructure, from sports fields to eco-friendly roofing, ensuring that the color lasts as long as the building itself.
Building Green Usage Areas
- Sports Surfaces: UV-stable green for tennis courts and running tracks.
- Artificial Turf Infill: Durable green coloring for rubber or sand granules.
- Concrete Roofing: Heat-stable green for tiles and solar-reflective roofs.
- Public Squares: Permanent green accents in urban paving designs.
Construction Green Specs
| Property | Standard Value | Unit |
| Cr2O3 Purity | Min 98.5 | % |
| Hardness (Mohs) | 8.0 - 8.5 | Scale |
| Oil Absorption | 15 - 25 | g/100g |
| Hegman Fineness | Min 6.0 | Hegman Units |
| Heat Stability | Up to 1000 | Degrees Celsius |
Attributes for Extreme Environments
- Chemical Immunity: Resistant to acids, alkalis, and industrial solvents.
- High Hardness: Provides excellent abrasion resistance in heavy-traffic areas.
- Low NIR Absorption: Natural "Cool Pigment" properties for thermal management.
- Permanent Hue: Will never fade, chalk, or turn grey over time.
Q: Is Chromium Oxide the same as Chrome Green?
A: No. Chromium Oxide (Cr2O3) is a single, extremely stable mineral. "Chrome Green" is often a blend of lead chromate and iron blue, which is much less stable and not eco-friendly.
Q: Can it be used in glass-reinforced concrete (GRC)?
A: Yes, its fine particle size and chemical inertness make it ideal for high-strength GRC applications.
High-Hardness Particle Engineering
We utilize specialized grinding technology to provide a "Low-Abrasion" grade of Chromium Oxide, which protects the mixing equipment while maintaining the pigment's legendary durability.
Solar-Reflective Blending: We offer custom green formulations that are specifically designed to meet "SRI" (Solar Reflectance Index) requirements for green building certifications like LEED.
The Science of Permanent Green
Color science in Chromium Oxide centers on "Spectral Stability." We monitor the reflectance curve to ensure it maintains a consistent "Olive" hue. Because it is a hard, crystalline material, we analyze the "Gloss Impact"—measuring how the particles interact with the surface texture of the concrete. We use CIELab data to ensure the green maintains its "a*" (greenness) value even when blended with white cement or other fillers, ensuring a vibrant, natural look that mimics the reflectance of natural vegetation.
