Product Details
Comprehensive information about our iron oxide pigments including specifications, applications, advantages, and more
Pigments Powder for Road Construction Materials
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
Infrastructure Solutions from Demi Pigment
Deqing Demi Pigment Technology Co., Ltd. is a key supplier to the civil engineering and infrastructure sector. Our pigments are manufactured to provide the long-term durability required for public works. We focus on the chemical stability of our powders, ensuring they remain non-reactive with the various admixtures used in modern high-performance concrete. Our materials are a standard choice for municipal projects where color is used to define space, improve safety, and enhance the urban environment.
Infrastructure Application Areas
- Concrete Block Paving: Coloring for sidewalks, plazas, and industrial flooring.
- Tactile Paving: High-visibility colors for safety indicators for the visually impaired.
- Road Curbing: Integral coloring for cast and precast roadside curbs.
- Bridge Components: Architectural coloring for structural bridge elements and railings.
Road Construction Material Specs
| Technical Parameter | Standard Value | Unit |
| Iron Oxide Content | Min 85 - 95 | % |
| Chloride Content | Max 0.01 | % |
| pH Stability | 6.0 - 8.5 | pH Units |
| Density | 4.5 - 5.0 | g/cm3 |
| Hegman Fineness | 6.0 - 7.0 | Hegman Units |
Attributes for Civil Engineering
- Salt Resistance: Unaffected by the application of sodium chloride or calcium chloride for snow removal.
- Alkali Stability: Remains stable in the high-pH environment of wet and cured concrete.
- Non-Migratory: Ensures that the color does not leach into the surrounding soil or water systems.
- Mechanical Durability: Pigment particles are physically integrated into the binder, resisting wear from heavy traffic.
Q: Can these pigments be used for airport runway markings?
A: Yes, our high-durability inorganic pigments are suitable for marking materials that require resistance to jet fuel and high-impact landings.
Q: Do they comply with EN 12878?
A: Our construction-grade pigments are manufactured to meet the requirements of EN 12878 (Category B) for reinforced concrete.
Precision Batching for Large Projects
We provide batch-to-batch consistency that is verified through digital colorimetry. This is essential for road projects where different sections are paved at different times but must match in color.
Environmental Documentation: We provide full technical data sheets (TDS) and safety data sheets (SDS) to ensure compliance with local construction and environmental regulations for infrastructure projects.
Visibility and Chromatic Engineering
The color science for road materials focuses on "Luminance Contrast." We provide CIELab L* values to help engineers calculate the visibility of safety markings and tactile paving under various lighting conditions (wet/dry, day/night). By optimizing the chroma and lightness of our pigments, we help create infrastructure that is not only aesthetically pleasing but also meets international safety standards for visual guidance and hazard warning.
