Product Details
Comprehensive information about our iron oxide pigments including specifications, applications, advantages, and more
Inorganic Iron Oxide Pigment Powder
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
The Global Benchmark in Inorganic Color
Deqing Demi Pigment Technology Co., Ltd. is a premier manufacturer of high-quality inorganic iron oxide powders. With decades of expertise, we have perfected the synthesis of mineral pigments that meet the most rigorous international standards. Our powders are the backbone of the global construction and coatings industries, known for their "Nature-Identical" properties and industrial-grade strength. We pride ourselves on delivering consistent, high-purity mineral solutions that empower our clients to build with confidence.
Inorganic Powder Usage Areas
- Cementitious Materials: Permanent coloring for concrete, mortar, and grout.
- Industrial Coatings: UV-stable pigments for heavy-duty protective paints.
- Plastic Masterbatch: Heat-resistant mineral colorants for polyolefins.
- Foundry Sands: High-heat identification and binder coloring for metal casting.
Inorganic Pigment Technical Specs
| Metric | Value | Standard |
| Iron Oxide Content | 90% - 98% | ISO 1248 |
| Lightfastness | Grade 8 (Excellent) | Blue Wool Scale |
| Alkali Resistance | Grade 5 (Excellent) | DIN 54001 |
| Sieve Residue (45$\mu$m) | Max 0.1% | ISO 787-7 |
| Water Soluble Salts | Max 0.3% | ISO 787-3 |
Core Characteristics
- UV Permanence: Zero degradation or fading under direct solar radiation.
- High Hiding Power: Excellent opacity reduces the required dosage in formulations.
- Eco-Friendly: Naturally occurring mineral structures that are safe for the environment.
- Non-Bleeding: Pigment particles stay physically locked in the matrix.
Q: Are inorganic pigments better than organic ones?
A: For outdoor and high-pH applications (like concrete), inorganic pigments are superior due to their extreme lightfastness and chemical stability.
Q: Can these powders be mixed?
A: Yes, all our inorganic powders are compatible and can be blended to create custom secondary shades.
Raw Material Precision
We provide "Ultra-Fine" micronized powders for specialized applications like inkjet inks or high-gloss plastics, ensuring a texture-free finish.
Global Logistics: Our packaging is designed for international sea freight, using moisture-proof, reinforced UV-stabilized bags to ensure the powder arrives in perfect condition.
The Science of Mineral Refractive Index
In inorganic science, we focus on the "Refractive Index" (RI) of the iron oxide crystal (RI≈2.4−3.0). This high index ensures that light is scattered efficiently at the surface, providing the "Total Hiding Power" that characterizes our powders. We use XRD (X-Ray Diffraction) to monitor the phase purity of each batch, ensuring the ratio of Hematite to Goethite is precisely controlled to maintain consistent color "Hue" and "Chroma" across our entire product range.
