Green Pigments Powder for Building Materials
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
Provider of High-Performance Green Pigments
Deqing Demi Pigment Technology Co., Ltd. is a specialist supplier of chromium oxide green for the construction and building material sectors. We provide a pigment that offers exceptional longevity and durability, even in the harshest climates. Our green powder is manufactured to high purity standards, ensuring it contains no harmful hexavalent chromium. It is the material of choice for infrastructure projects and high-end architectural finishes where performance and color retention are non-negotiable.
Building Material Green Usage
- Concrete Roofing Tiles: Durable green coloring for residential and industrial roofs.
- Industrial Flooring: Pigmentation for high-wear epoxy and cementitious floors.
- Exterior Renders: Weather-resistant green finishes for facades.
- Pavers and Tiles: Color-coding for bike lanes and decorative urban areas.
Green Building Material Specs
| Property | Typical Value | Standard |
| Cr2O3 Content | Min 98 | % |
| Oil Absorption | 10 - 20 | g/100g |
| Hardness (Mohs) | 8 - 8.5 | Mineral Standard |
| Melting Point | 2435 | Degrees Celsius |
| Water Soluble Matter | Max 0.3 | ISO 787-3 |
Functional Attributes for Green Materials
- Extreme Weatherability: No change in color after years of exposure to salt, sun, and acid rain.
- Abrasive Resistance: The high hardness of the pigment enhances the wear resistance of the surface.
- Heat Reflection: High NIR reflectance contributes to "cool" building surfaces.
- Alkali and Acid Proof: Completely unaffected by the most aggressive environmental pollutants and building chemicals.
Q: Is chromium oxide green safe for the environment?
A: Yes, our chromium oxide green is in the stable trivalent (Cr3+) state, which is non-toxic and environmentally safe for use in building materials.
Q: Does it have the same tinting strength as iron oxides?
A: Chromium oxide green has a slightly different tinting profile but generally provides excellent opacity and coverage at similar dosage rates (3-6%).
Precision Green Manufacturing
We provide various shades of green, from light "sage" tones to deep "forest" greens. Our technical team can also provide micronized versions for applications requiring high surface smoothness.
Global Compliance: Our green pigments are tested for heavy metal content to ensure they meet the environmental regulations of the EU, USA, and other global markets, supporting the green building initiatives of our clients.
The Science of Solar Reflective Green
Green color science in building materials focuses on the "Total Solar Reflectance" (TSR). Chromium oxide green has a unique spectral signature that reflects significant energy in the near-infrared spectrum. We measure this using UV-VIS-NIR spectrophotometry. By optimizing the particle size and purity of our green pigments, we help manufacturers create materials with high TSR values, which helps mitigate the urban heat island effect and improves the energy efficiency of buildings. We provide complete spectral data to support LEED and other green building certifications.
