Mineral Pigments for Building Products
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
The Mineral Backbone of Modern Construction
Deqing Demi Pigment Technology Co., Ltd. is the global supply partner for manufacturers of diverse building materials. We provide the "Color of Architecture," supporting the production of materials that are as beautiful as they are functional. Our mineral series is the industry standard for manufacturers who need a reliable, high-volume source of color that doesn't compromise on safety or environmental responsibility. We are proud to contribute to the construction of sustainable, colorful, and long-lasting buildings.
Building Product Usage Areas
- Roofing Materials: Permanent coloring for concrete and clay tiles.
- Wall Systems: Integral color for gypsum, fiber-cement, and insulation panels.
- Masonry Units: Consistent coloring for bricks and natural stone veneers.
- Jointing Materials: High-purity colorants for industrial caulks and sealants.
Building Grade Technical Specs
| Metric | Value | Standard |
| Thermal Stability | 180∘C−800∘C (Grade dependent) | DIN 53772 |
| VOC Content | 0% (Inorganic Mineral) | ISO 11890 |
| Weathering (1000h) | ΔE<1.0 | ASTM G154 |
| pH Range Compatibility | 3.0 - 13.0 | Internal Method |
| Oil Absorption | 20 - 30 g/100g | ISO 787-5 |
Product Advantages
- Inherent Fire Resistance: Mineral pigments are non-combustible and heat-stable.
- Sustainable Profile: Ideal for products seeking Green Building certifications.
- Zero Migration: The color will not "bleed" out of the product onto other surfaces.
- Extreme Weathering: Proven performance in tropical, desert, and arctic conditions.
Q: Are these pigments safe for indoor air quality?
A: Absolutely. Being inorganic minerals, they contain no solvents or VOCs and are chemically inert once integrated into a product.
Q: Do they work in gypsum-based products?
A: Yes, they are highly compatible with gypsum, providing smooth and uniform coloring without affecting the drying time.
Environmental Documentation Services
We provide "Health Product Declarations" (HPD) and full MSDS for all our building-grade pigments to support your product's compliance with safety and environmental laws.
Consolidated Supply Chain: We can provide a single-source solution for all the colorants used in your factory, from the structural brick to the mortar and the roof tile.
The Science of Thermal Efficiency
In building products, we focus on the "Solar Reflectance Index" (SRI). Certain mineral pigments are optimized to reflect the Near-Infrared (NIR) portion of the solar spectrum. By choosing pigments with a high SRI, manufacturers can create roofing and wall products that reduce the "Heat Gain" of a building, lowering energy costs for cooling and contributing to more sustainable urban environments. We monitor the "TSR" (Total Solar Reflectance) to ensure our colors are as "Cool" as possible.
