Product Details
Comprehensive information about our iron oxide pigments including specifications, applications, advantages, and more
Fine Grade Brown Iron Oxide
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
Micro-Level Precision for Premium Aesthetics
Deqing Demi Pigment Technology Co., Ltd. is the master of "Fine Mineral Science." We recognize that in premium coatings, the texture is as important as the color. Our fine-grade brown is produced using advanced pearl-milling to ensure a silky-smooth consistency. We provide the "Precision Brown" that allows our clients to achieve sophisticated, high-saturation finishes in their most delicate industrial and consumer products.
Fine Grade Brown Usage Areas
- High-Gloss Enamels: Smooth, deep brown for kitchen cabinetry and furniture.
- Thin-Film Plastics: Streak-free coloring for electronic housings and fibers.
- Packaging Inks: High-opacity, fine-grind brown for premium labels and cartons.
- Automotive Refinish: Base-coat browns for metallic and pearl vehicle finishes.
Fine Brown Technical Specs
| Metric | Value | Method |
| Hegman Fineness | Min 7.5 | ISO 1524 |
| Average Particle Size | 0.25 - 0.45 μm | Laser Diffraction |
| Oil Absorption | 25 - 35 g/100g | ISO 787-5 |
| Iron Content | Min 92% | ISO 1248 |
| Tinting Strength | 105% - 110% | Vs. Std Brown |
Performance Characteristics
- Superior Gloss: Small particles minimize light scattering for a high-shine finish.
- Intense Color: Higher surface area provides more "punch" per gram of pigment.
- Non-Abrasive: Fine particles protect delicate printing heads and spray nozzles.
- Rapid Wetting: Designed for instant incorporation into modern liquid resins.
Q: Does "Fine" mean it's harder to handle?
A: No. It disperses faster than standard grades, though we recommend using it in a low-dust system due to its high fineness.
Q: Is it suitable for water-based stains?
A: Yes, its fine grind ensures it penetrates wood pores deeply and stays in suspension longer.
Technical Lab Services
We offer "Gloss-Curve Profiling," showing exactly how our fine brown maintains the surface integrity of your specific resin at various loading levels.
Custom Micronization: We can mill the brown oxide to your specific D90 requirements for ultra-thin coating applications.
The Science of Surface Charge Stabilization
In fine-grade brown, the primary scientific challenge is preventing "Re-agglomeration." Because the particles are so small, they naturally want to clump back together. We manage this through "Zeta Potential Optimization," ensuring that each particle carries a uniform surface charge. This creates a "Molecular Repulsion" that keeps the particles separate. This scientific "Dispersion Guard" is what ensures that our fine brown delivers a perfectly smooth, seed-free finish in every application.
