High Stability Oxide Pigments for Construction
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
Engineering Longevity into Every Structure
At Deqing Demi Pigment Technology Co., Ltd., we recognize that some projects demand more than standard materials. Our high-stability construction series is designed for the most rigorous specifications. We use advanced purification techniques to ensure our pigments are free from the contaminants that cause structural or aesthetic issues. We provide the "Performance-Grade" color that protects your investment and ensures your project looks as good in 50 years as it does on opening day.
High-Stability Usage Areas
- Marine Infrastructure: Salt-resistant color for docks, piers, and coastal walls.
- Public Monuments: Fade-proof color for landmarks and sculptures.
- Self-Leveling Floors: Stable, uniform color for high-precision industrial flooring.
- High-End Precast: Luxury architectural panels with tight color tolerances.
High Stability Technical Specs
| Metric | Value | Standard |
| Soluble Chlorides | < 0.01% | ISO 787-13 |
| Total Heavy Metals | < 100 ppm | Standard Compliance |
| Color Tolerance (ΔE) | Max 0.5 | CIELAB |
| Sieve Residue (325 mesh) | Max 0.1% | ISO 787-7 |
| Moisture Content | Max 0.3% | ISO 787-2 |
Performance Characteristics
- Efflorescence Control: Ultra-low salt content prevents unsightly white surface deposits.
- Exceptional Uniformity: Tight batch-to-batch control for large-scale color matching.
- Corrosion Resistance: Does not contain chlorides that could attack steel reinforcement.
- Maximized Dispersion: Faster "wet-out" times in high-speed concrete plants.
Q: Why is "High Stability" better for reinforced concrete?
A: These grades have extremely low chloride levels, which is critical to prevent the corrosion of the internal steel rebar.
Q: How does it help with efflorescence?
A: By removing soluble minerals during manufacturing, we reduce the "fuel" that causes white salt crystals to form on the surface.
Advanced Architectural Support
We offer "Efflorescence Risk Assessment," testing your concrete mix with our pigments to ensure the best possible aesthetic outcome.
Custom Lab* Matching: We can calibrate our high-stability pigments to match specific RAL or Pantone colors for corporate architectural standards.
The Science of Osmotic Pressure Mitigation
Efflorescence is driven by "Osmotic Pressure"—water carrying dissolved salts to the concrete surface where they crystallize. By utilizing "Ultra-Washed" high-stability oxides, we reduce the "Electrolyte Concentration" within the pigment itself. This scientific purification process means that even if water penetrates the concrete, there are fewer mobile ions to be transported to the surface. The result is a cleaner, deeper color that is naturally resistant to the "whitening" effect common in standard pigmented concrete.
