Brown Iron Oxide for Construction Use
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
Building with the Depth of Natural Stone
At Deqing Demi Pigment Technology Co., Ltd., we provide the "Architectural Anchor" for the construction world. We recognize that brown is the foundation of natural-looking landscapes. Our construction-grade brown is manufactured to stay vibrant for decades. We provide the "Inorganic Stability" that allows urban developers to create warm, inviting public spaces with the total confidence that the color will never wash out or fade.
Construction Brown Usage Areas
- Decorative Pavers: Producing realistic wood and stone effects in concrete.
- Roofing Shingles: Durable, heat-stable brown for ceramic-coated granules.
- Exterior Stucco: Providing earthy base tones for architectural renders.
- Stamped Concrete: Essential for high-contrast "Antique" release agents and base colors.
Construction Brown Specs
| Metric | Value | Standard |
| Alkali Resistance | Grade 5 (Maximum) | DIN EN 12878 |
| Lightfastness | 8 (Blue Wool Scale) | ISO 105-B02 |
| Chloride Content | Max 0.1% | ASTM C979 |
| Water Solubles | Max 0.5% | ISO 787-3 |
| Tinting Strength | 100% ± 5% | ISO 787-24 |
Core Advantages
- Lime-Proof: Chemically unaffected by high-pH cement environments.
- Non-Fading: Pure mineral structure is immune to solar radiation.
- Rebar Safe: Low salt profile prevents corrosion of embedded steel.
- Rapid Dispersion: Breaks down easily in industrial concrete mixers.
Q: Can I achieve a "Wood-Look" with this pigment?
A: Yes, it is the primary pigment used for wood-textured concrete planks and outdoor furniture.
Q: Will it turn red over time?
A: No. Our synthetic brown is a pre-stabilized blend that maintains its specific hue regardless of weather exposure.
Construction Logistics Services
We offer "Batch-Ready Dosing," providing brown oxide in pre-weighed, water-soluble bags for precise, dust-free integration at the job site.
Heritage Color Matching: We can formulate specific browns to match historic stone or brickwork for restoration projects.
The Science of Particulate Interlocking
In construction brown, the science lies in "Pore Filling." Since brown oxide is a blend of red, yellow, and black particles, it has a broader "Particle Size Distribution." This scientific profile allows the pigment to pack more densely into the microscopic voids of the concrete matrix. This results in "Integral Coloration," where the pigment isn't just a surface coating but a structural part of the concrete, significantly increasing the material's resistance to surface wear and color loss.
