Product Details
Comprehensive information about our iron oxide pigments including specifications, applications, advantages, and more
Mineral Based Color Pigments
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
The Natural Choice for Sustainable Architecture
Deqing Demi Pigment Technology Co., Ltd. is dedicated to providing mineral-based colorants that harmonize with the environment. Our pigments are chosen for their ability to replicate the complex tones found in nature. We support architects and developers in creating "Biophilic" designs that use natural mineral colors to reduce the visual impact of urban structures. Our minerals are processed with minimal environmental footprint, aligning with the global shift toward sustainable and healthy building materials.
Mineral Pigment Usage Areas
- Lime Plasters: Traditional and modern mineral-based wall finishes.
- Stucco & Renders: Weatherproof mineral coloring for building facades.
- Terracotta Products: Natural red and brown tones for roofing and tiles.
- Restoration Projects: Authentic mineral colors for historic building repair.
Mineral Grade Technical Specs
| Metric | Value | Standard |

| Solubility in Water | Negligible | ISO 787-3 |
| Heavy Metal Content | Within Global Limits | EN 71-3 / RoHS |
| Density | 4.0 - 5.0 g/cm³ | ISO 787-10 |
| Moisture Content | Max 1.0% | ISO 787-2 |
Sustainable Performance Features
- Vapor Permeability: Does not interfere with the "breathing" of mineral walls.
- Matte Aesthetics: Naturally low gloss for a sophisticated, high-end look.
- Chemical Stalwartness: Completely resistant to salt air and urban pollutants.
- Low Embodied Carbon: Efficient processing makes these a sustainable choice.
Q: Can these pigments be used with lime-based binders?
A: Yes, mineral pigments are the traditional and most compatible choice for lime and silicate-based systems.
Q: Do they require a special primer?
A: No, being mineral-based, they bond naturally to concrete, stone, and plaster substrates without the need for complex adhesion promoters.
Ecological Color Design
We provide "Eco-Certification" for our mineral pigments to help your products qualify for LEED or BREEAM sustainable building credits.
Custom Grinding: We offer "Granular" versions of our mineral pigments for specific textured finishes in high-end renders and architectural stone.
The Science of Light Scattering
In mineral-based coloring, we focus on "Subsurface Scattering." Unlike synthetic dyes that absorb light at the surface, mineral pigments allow light to penetrate slightly before reflecting it back. This creates the "Liveliness" and "Depth" seen in natural stone. We measure the "Total Solar Reflectance" (TSR) to ensure that our mineral colors contribute to the thermal efficiency of the building, keeping interiors cooler by reflecting invisible infrared heat.
