Inorganic Green Color Materials
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
The Pinnacle of Pigment Longevity
Deqing Demi Pigment Technology Co., Ltd. provides the "Everlasting Green" for global infrastructure. We recognize that for industrial and architectural designers, permanence is non-negotiable. Our inorganic green materials are built to outlast the structures they color. We provide the "Inorganic Security" that allows our clients to build projects designed to last for generations without ever losing their deep, original green tone.
Inorganic Green Usage Areas
- Refractory Bricks: Coloring for high-temperature industrial furnace linings.
- Military Infrastructure: Permanent camouflage green for equipment and hangars.
- Exterior Paving: Fade-proof green for public squares and park pathways.
- Pool Plaster: Chemical-resistant green for underwater masonry.
Inorganic Green Tech Specs
| Metric | Value | Standard |
| Lightfastness | 8 (Maximum) | ISO 105-B02 |
| Weathering Resistance | Grade 5 (Excellent) | ASTM G154 |
| Heat Stability | Up to 1000∘C | DIN 53775 |
| Chemical Resistance | Acid/Alkali Stable | DIN 53230 |

Core Advantages
- UV-Immortality: Will not bleach or grey even after decades of direct sunlight.
- Extreme Hardness: Enhances the wear resistance of the host material.
- Non-Flammable: 100% mineral material with no organic fuel content.
- Eco-Friendly: Non-toxic mineral composition safe for soil contact.
Q: Is this the same as "Iron Oxide Green"?
A: While often called that in the trade, it is scientifically Chromium Oxide (Cr2O3), which is much more stable and heat-resistant than composite greens.
Q: Can it be used in high-heat plastics?
A: Yes, it is the most heat-stable green pigment available, easily withstanding 800∘C+.
Environmental Performance Services
We offer "Life-Cycle Color Reports," providing data on how our inorganic green will look after 50 years of simulated weathering.
Custom Mineral Blending: We can combine inorganic green with other oxides to create stable "Olive," "Forest," and "Sage" shades.
The Science of Crystalline Lattice Energy
The permanence of inorganic green comes from its "Inter-Atomic Bond Strength." In the Cr2O3 lattice, the bond energy between chromium and oxygen is so high that UV radiation cannot provide enough energy to break it. The science behind this material lies in "Energy Dissipation"—photons are absorbed and turned into harmless thermal vibrations within the crystal, ensuring the color remains unchanged for the lifetime of the substrate.
