Construction Grade Iron Oxide Pigment Types
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
Defining the Color of the Modern World
Deqing Demi Pigment Technology Co., Ltd. is a leading manufacturer of all construction-grade pigment types. We recognize that for builders, color is only as good as its durability. Our "Type" classification system helps project managers select the right mineral for the job—whether it's a high-vibrancy red for a plaza or a stable black for an asphalt road. We provide the "Inorganic Integrity" that ensures your construction projects look as good in twenty years as they do today.
Construction Type Usage Areas
- Type R (Red): Roof tiles, pavers, and high-visibility safety zones.
- Type Y (Yellow): Stucco, renders, and decorative "Ochre" masonry.
- Type BK (Black): Asphalt coloring, concrete blocks, and "Gunmetal" finishes.
- Type BR (Brown): Natural stone imitation and landscape architecture.
Construction Type Comparison
| Type | Chemical Formula | Main Advantage |
| Red | α−Fe2O3 | Highest UV Stability |
| Yellow | α−FeOOH | Excellent Value/Chroma |
| Black | Fe3O4 | Maximum Hiding Power |
| Brown | Blend | Natural Earth Shades |
Performance Characteristics
- Lime-Proof: All types are chemically inert in the presence of curing cement.
- Fade-Resistant: Inorganic mineral bonds are unaffected by intense sunlight.
- Freeze-Thaw Stable: Does not absorb water or disrupt the concrete's physical matrix.
- Safe for Environment: Non-toxic minerals that meet all structural safety codes.
Q: Are all types "Safe" for reinforced concrete?
A: Yes, our construction types are processed to have very low chloride and sulfate levels, ensuring no corrosion to steel rebar.
Q: Can I mix different types together?
A: Absolutely. Red, Yellow, and Black types can be blended on-site to create custom oranges, tans, and greys.
Construction Engineering Services
We offer "Strength-Impact Testing," providing data to prove our pigment types do not weaken your concrete mix design.
Custom Blended Types: We can provide pre-mixed "Type-Terracotta" or "Type-Sandstone" to simplify your on-site batching process.
The Science of Particulate Locking
The durability of construction types is due to "Substrate Encapsulation." When cement hydrates, it forms a microscopic needle-like structure. Our pigment types are sized to fit within these "Lattice Voids." This scientific "Locking" ensures the pigment is not just a surface coating but is physically trapped within the stone. Because iron oxides are chemically similar to the minerals in the cement itself, they bond perfectly, providing a color that is as permanent as the building itself.
