Inorganic Oxide Color Pigment Materials
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
The Foundation of Permanent Color
Deqing Demi Pigment Technology Co., Ltd. is dedicated to the science of longevity. We believe that color should be a permanent feature of a product, not a temporary coating. Our inorganic oxide series is the result of rigorous chemical engineering, designed to provide the world's most stable color palette. We provide the "Elemental Reliability" that architects, engineers, and product designers depend on for their most important projects.
Inorganic Material Usage Areas
- Architectural Concrete: Permanent color for precast panels and facades.
- Composite Decking: UV-stable coloring for wood-plastic composites (WPC).
- Roofing Materials: Durable color for concrete tiles and asphalt shingles.
- Industrial Ceramics: High-heat stable colorants for technical ceramic parts.
Inorganic Material Technical Specs
| Metric | Value | Standard |
| Lightfastness | Grade 8 (Maximum) | ISO 105-B02 |
| Weatherability | Excellent | ASTM G154 |
| Heat Resistance | Up to 800∘C | Internal Method |
| Alkali Resistance | Grade 5 | ISO 105-B02 |
| Moisture Content | Max 0.3% | ISO 787-2 |
Product Characteristics
- UV Immortality: The inorganic structure is completely unaffected by solar radiation.
- Zero Migration: Colors will not "leak" or "bleed" between different material layers.
- Non-Hazardous: Pure mineral composition is safe for both indoor and outdoor environments.
- High Density: Provides excellent coverage and opacity in all types of binders.
Q: Why are inorganic pigments better than organic for outdoor use?
A: Inorganic pigments have a rigid mineral lattice that doesn't break down under UV light, whereas organic dyes have carbon bonds that "snap" in the sun.
Q: Are they compatible with recycled materials?
A: Yes, they are highly stable and can withstand the multiple heat cycles required in recycling processes.
Material Science Consulting
We provide "Material Lifecycle Analysis," showing how our pigments will look after 20+ years of simulated environmental exposure.
Custom Material Blends: We can create specialized pigment-carrier systems (e.g., pellets or liquids) to ensure perfect integration into your specific material matrix.
The Science of Spectral Permanence
The permanence of inorganic oxides is rooted in their "Band-Gap" electronics. Most colorants fade because electrons are "pushed" out of their orbits by high-energy UV photons. In our inorganic oxide materials, the energy required to do this is far higher than what natural sunlight provides. This "Energy Barrier" is the reason why these pigments have been found vibrant in 30,000-year-old cave paintings. We harness this natural physics to provide industrial-scale color that simply does not change.
