Durable Ferric Green Colorants
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
Protecting the Vision of a Green World
At Deqing Demi Pigment Technology Co., Ltd., we define durability as the survival of color in the most punishing conditions. We understand that for outdoor green spaces and infrastructure, color failure is not acceptable. Our durable ferric green series is the result of advanced stabilization technology. We provide the "Maintenance-Free" green solutions that allow designers to specify vibrant, natural tones with absolute confidence in their long-term performance.
Durable Green Usage Areas
- Infrastructure Marking: Permanent green for cycle paths and accessible zones.
- Bridge Coatings: High-durability green for steel and concrete protection.
- Public Parks: Fade-proof green for benches, signage, and playground bases.
- Architectural Stuccos: Stable green tones for exterior thermal insulation systems.
Stability Grade Technical Specs
| Metric | Value | Standard |
| Weathering (QUV) | ΔE<1.5 (1500h) | ASTM G154 |
| Lightfastness | Grade 7-8 | ISO 105-B02 |
| Oil Absorption | 25 - 30 g/100g | ISO 787-5 |
| Specific Gravity | 3.5 - 4.5 g/cm³ | ISO 787-10 |
| Hiding Power | Excellent | Visual Assessment |
Performance Characteristics
- Anti-Fading: Specifically protected against UV degradation and atmospheric bleaching.
- Pollutant Resistant: Unaffected by acid rain, SO2, and urban nitrogen oxides.
- Superior Adhesion: Works with the binder to form a tough, color-stable film.
- Non-Chalking: Maintains a smooth surface and prevents "whitening" over decades.
Q: How long will this green last outdoors?
A: Our durable series is designed to maintain its color for 10-15+ years depending on the binder and exposure levels.
Q: Is it resistant to cleaning chemicals?
A: Yes, its mineral-heavy structure is resistant to most detergents and mild industrial solvents.
Longevity Technical Services
We provide "Exposure Verification Testing," where we test your final product in our weathering chambers to provide an estimated color life.
Custom UV-Stabilizer Integration: We can offer "Enhanced Grades" where we incorporate additional UV absorbers into the pigment powder for extreme desert or tropical environments.
The Science of Spectral Shielding
The durability of our ferric green comes from "Sacrificial Energy Dissipation." By incorporating specific mineral additives that absorb high-energy UV photons, we prevent that energy from reaching the organic blue components of the pigment. This scientific "Shielding Effect" preserves the molecular bonds of the color-producing agents. This ensures that the green light reflectance remains constant, providing a "Permanently Fresh" look that resists the "Burning Out" typical of standard green dyes.
