Comprehensive information about our iron oxide pigments including specifications, applications, advantages, and more
Paint Grade Iron Oxide Pigments
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
Excellence in Every Micron
Deqing Demi Pigment Technology Co., Ltd. is a premier partner for the global paint and coating industry. We understand that in paint manufacturing, the quality of the pigment determines the quality of the brand. Our paint-grade series is produced in a state-of-the-art facility where particle size is monitored in real-time. We provide the "Pure Color" that allows paint manufacturers to create stable, durable, and beautiful coatings that protect and enhance surfaces worldwide.
Paint Grade Usage Areas
- Architectural Enamels: High-gloss and matte finishes for interior and exterior walls.
- Anti-Corrosive Primers: Red iron oxide primers for steel and metal structures.
- Wood Stains: Fine-milled browns for transparent and opaque wood finishes.
- Powder Coatings: Heat-stable mineral colors for industrial metal finishing.
Paint Grade Technical Specs
| Metric | Value | Standard |
| Hegman Fineness | 6.0 - 7.5 | ISO 1524 |
| Oil Absorption | 15 - 25 g/100g | ISO 787-5 |
| pH Value | 5.5 - 7.5 | ISO 787-9 |
| Volatile Matter (105∘C) | Max 0.5% | ISO 787-2 |
| Tinting Strength | 100% ± 2% | ISO 787-24 |
Performance Characteristics
- Rapid Dispersion: Designed for high-speed "Dissolver" mixing equipment.
- Exceptional Opacity: High refractive index ensures one-coat hiding capability.
- Chemical Stability: Resistant to solvents, water-borne acids, and atmospheric pollutants.
- Texture-Free: Micronization ensures a glass-smooth surface without "grittiness."
Q: Can these pigments be used in water-borne systems?
A: Yes, our paint-grade series is treated to be easily wettable in both solvent-based and water-based resin systems.
Q: Are they suitable for automotive refinishing?
A: Absolutely. Our high-chroma reds are a standard choice for durable automotive primers and basecoats.
Advanced Milling Customization
We offer "Sub-Micron Milling" for specialized thin-film coatings where the total film thickness is less than 20 microns.
Liquid Master-Batching: For large-scale paint producers, we can provide pre-dispersed pigment concentrates to eliminate the grinding step in your manufacturing process.
The Science of Light Absorption
In paint science, we focus on "Mie Scattering." By controlling the particle size to approximately 0.2 to 0.4 microns, we maximize the pigment's ability to scatter light, which provides its "Opacity." We use spectrophotometry to ensure that the "L*" (Lightness) and "C*" (Chroma) are consistent, preventing "metamerism"—where the paint looks different under fluorescent light versus natural sunlight.
