Comprehensive information about our iron oxide pigments including specifications, applications, advantages, and more
Fine Particle Red Oxide Pigment
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
The Pinnacle of Pigment Fineness
At Deqing Demi Pigment Technology Co., Ltd., we push the limits of mineral milling. We recognize that in the world of high-gloss paints and delicate inks, particle size is everything. Our fine-particle red series is produced using advanced pearl-milling technology. We provide the "Micro-Precision" that enables our clients to achieve mirror-like finishes and intense, transparent color effects that were previously impossible with inorganic minerals.
Fine Red Usage Areas
- High-Gloss Enamels: Smooth, vibrant red for appliance and furniture finishes.
- Flexographic Inks: High-opacity, fine-grind red for packaging and labels.
- Automotive Refinish: Precision color matching for vehicle repair coatings.
- Thin-Wall Plastics: Streak-free coloring for films, fibers, and delicate moldings.
Fine Particle Technical Specs
| Metric | Value | Standard |
| Average Particle Size (D50) | 0.1 - 0.25 μm | Laser Diffraction |
| Hegman Fineness | Min 7.5 | ISO 1524 |
| Oil Absorption | 25 - 35 g/100g | ISO 787-5 |
| Iron Content (Fe2O3) | Min 98% | ISO 1248 |
| Tinting Strength | 105% - 110% | Vs. Std Red |
Performance Features
- Superior Gloss: Minimizes light scattering at the surface for a high-shine finish.
- Intense Tinting: Higher surface area provides more color per gram of pigment.
- Rapid Wetting: Finely ground particles incorporate quickly into liquid resins.
- Ultra-Smooth Texture: Eliminates "seeds" and surface roughness in thin coatings.
Q: Does a smaller particle size mean it will fade faster?
A: No. It is still 100% inorganic hematite. The lightfastness remains at the maximum level (Grade 8).
Q: Is it harder to disperse because it is so fine?
A: It requires high-shear mixing, but because the particles are so small, it actually reaches its "Full Tint" faster than larger-grade oxides.
Ink & Coating Lab Services
We offer "Dispersion Curve Analysis," showing you exactly how long it takes for our fine red to reach its maximum Hegman value in your resin.
Custom Surface Modification: We can provide "Pre-Wetted" or hydrophobic-treated fine reds for instant integration into solvent-based inks.
The Science of Surface Area Energy
Fine particle oxides operate on the principle of "Increased Interfacial Area." By reducing the particle size, we increase the surface area available to interact with light. The science of our milling process ensures that these particles don't "Re-agglomerate" (clump back together). We use specialized surfactants that act as "Molecular Spacers," keeping each fine red particle separate. This ensures that the pigment reflects light as a massive number of tiny mirrors, resulting in the high-chroma, high-gloss effect required for premium finishes.
