High Stability Green Oxide Colorants
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
Setting the Standard for Color Durability
Deqing Demi Pigment Technology Co., Ltd. specializes in high-end mineral solutions for the most demanding global industries. We understand that stability is the foundation of trust in industrial manufacturing. Our high-stability green series undergoes rigorous testing to ensure it exceeds international standards for lightfastness and weatherability. We provide the technical assurance that your products will remain visually consistent and structurally sound in any climate.
High Stability Green Usage Areas
- Railway & Infrastructure: Permanent green signaling and safety markings.
- Chemical Processing Plants: Corrosion-resistant coatings for tanks and pipes.
- Solar Energy Components: Heat-stable colorants for thermal collectors.
- Military Equipment: Low-reflectance, high-durability tactical coatings.
Technical Specs: Stability Grade
| Metric | Value | Standard |
| Heat Resistance | 800∘C−1000∘C | DIN 53772 |
| Weathering (2000h) | ΔE < 1.0 | ISO 4892 |
| PH Resistance | Range 1 - 13 | Internal Method |
| Oil Absorption | 15 - 20 g/100g | ISO 787-5 |
| Water Solubles | Max 0.1% | ISO 787-3 |
Core Advantages
- Thermal Immortality: Does not decompose or shift shade at peak industrial temperatures.
- Total Alkali Stability: Perfect for use in high-calcium cement and lime systems.
- Non-Leaching: Pigment particles remain permanently embedded in the host material.
- Low Oil Absorption: Allows for high pigment loading without compromising resin flow.
Q: Can this green survive in high-alkaline environments?
A: Yes, it is specifically designed to be stable in systems with a PH as high as 13, such as fresh concrete.
Q: Does it contain any organic components?
A: No, this is a 100% inorganic mineral oxide, ensuring maximum stability and longevity.
Advanced Stability Testing
We offer "Xenon Arc Weathering Reports" to demonstrate how our green colorants perform over simulated 10-year exposure periods.
Custom Surface Passivation: For highly reactive chemical environments, we can provide pigments with specialized silica or alumina coatings for extra protection.
The Science of Thermodynamic Stability
In these high-stability grades, we focus on "Enthalpy of Formation." By synthesizing the oxide at specific high-energy states, we create a pigment that is thermodynamically "content." It has no chemical drive to react with acids, alkalis, or oxygen. This "Passivity" is what ensures that the green hue remains unchanged even when the surrounding material is under extreme stress. We utilize Differential Scanning Calorimetry (DSC) to verify that no phase changes occur within your required temperature range.
