High Stability Oxide Pigment Powders
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
Engineering Stability into Every Batch
At Deqing Demi Pigment Technology Co., Ltd., stability is our core specialty. We recognize that in many technical applications, a standard pigment is not enough. Our "High Stability" series is designed for the perfectionist manufacturer. We use advanced synthesis techniques to ensure that our pigments maintain their crystal structure and color profile even under extreme manufacturing and end-use stress. We provide the stability that protects your brand's reputation for quality.
High Stability Usage Areas
- Marine Topcoats: UV and salt-stable color for maritime vessels.
- Engineering Plastics: Heat-stable coloring for Polyamide (PA) and PBT resins.
- Industrial Ovens: Heat-resistant coatings for high-temperature equipment.
- External Signage: Long-term color retention for municipal and safety signs.
High Stability Technical Specs
| Metric | Value | Standard |
| Heat Stability | Up to 400∘C | DIN 53772 |
| Weathering (ΔE) | < 1.0 (1000h) | ISO 4892 |
| Salt Spray Resistance | Grade 5 (Maximum) | ASTM B117 |
| Oil Absorption | 15 - 25 g/100g | ISO 787-5 |
| Specific Resistance | Min 3000 Ω⋅cm | ISO 787-14 |
Performance Attributes
- Phase-Locked Color: Crystal structure does not shift, preventing "shade drift" during heating.
- Superior Dispersibility: Surface treatments reduce clumping and speed up mixing.
- Anticorrosive Synergy: Dense mineral structure helps block moisture and oxygen.
- Consistent Lab* Values: Guaranteed color matching from batch to batch.
Q: What makes these "High Stability" compared to standard grades?
A: These grades feature higher iron purity, more controlled particle sizes, and advanced surface treatments to resist external stress.
Q: Can they be used in acidic environments?
A: Yes, our passivated high-stability grades offer enhanced resistance to mild acids compared to standard oxides.
Technical Performance Audits
We offer "High-Heat Stress Testing" for your specific polymer or resin, providing you with detailed color-shift data at different temperatures.
Custom Surface Passivation: We can adjust the thickness and type of inorganic surface coating to meet your specific chemical resistance requirements.
The Science of Surface Passivation
In high-stability pigments, we focus on "Coating Integrity." By applying a nano-layer of Silicon Dioxide (SiO2) or Aluminum Oxide (Al2O3) around the iron oxide core, we create a physical barrier. This barrier prevents "Electron Transfer" between the pigment and the surrounding resin. This not only keeps the color stable but also prevents the pigment from acting as a catalyst for resin degradation (yellowing), ensuring that both the color and the material stay strong for their entire service life.
