Comprehensive information about our iron oxide pigments including specifications, applications, advantages, and more
Durable Red Oxide 130 Colorants
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
Building a Legacy with Permanent Color
At Deqing Demi Pigment Technology Co., Ltd., we build colors that stand up to time. We understand that for public works and high-end architecture, the color is part of the project's legacy. Our durable 130 series is synthesized to provide a level of stability that surpasses international standards. We provide the "Maintenance-Free" color solutions that allow designers to specify warm, vibrant reds with total confidence in their lifelong performance.
Durable Red 130 Usage Areas
- Civic Architecture: Fade-proof red for city halls, museums, and public spaces.
- Safety Marking: Long-term red for cycle paths, pedestrian crossings, and helipads.
- Exterior Stucco: Color-stable red for modern architectural wall finishes.
- Public Infrastructure: Permanent red for bridges, dams, and sound barriers.
Durability Grade Technical Specs

| Lightfastness | Grade 8 (Maximum) | ISO 105-B02 |
| Oil Absorption | 18 - 25 g/100g | ISO 787-5 |
| Salt Spray Resistance | High | ISO 9227 |
| Hiding Power | Superior | Contrast Ratio |
Performance Features
- UV Immortality: The inorganic crystal structure is physically incapable of being broken by natural sunlight.
- Pollutant Shield: Resistant to urban smog, acid rain, and coastal humidity.
- Zero Migration: Pigment is completely insoluble and will not "bleed" or "halo" in the substrate.
- Non-Chalking: Maintains surface gloss and color depth for the entire service life.
Q: Will this red turn brown in the sun?
A: No. Grade 130 is chemically stable. Its color is a fundamental property of the mineral and cannot "bleach" or darken naturally.
Q: Is it safe for eco-friendly building certifications (LEED)?
A: Yes, our durable oxides are natural-based, non-toxic, and contribute to the longevity and sustainability of the building.
Longevity Technical Support
We provide "Accelerated Weathering Certifications," giving you the technical data needed to secure municipal and government infrastructure contracts.
Custom Shade Profiling: We can calibrate our durable 130 to match specific regional "Historic Reds" for heritage restoration projects.
The Science of Reflectance Preservation
The durability of our Red 130 colorants is rooted in "Lattice Stability." In most pigments, light energy promotes an electron to a state that can break chemical bonds. In synthetic hematite, these transitions are "Forbidden" or occur within protected electronic shells. This means the energy is absorbed and released as harmless heat, leaving the crystal structure perfectly intact. This scientific property is why our red pigments remain vibrant after decades of intense tropical sun—the color is literally locked in stone.
