Iron Oxide Pigment Grade Comparison
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
Expert Guidance for Pigment Selection
At Deqing Demi Pigment Technology Co., Ltd., we believe that "Knowledge is Color." We recognize that the wide variety of iron oxide grades can be overwhelming for procurement and engineering teams. Our grade comparison guide is designed to simplify the selection process. We provide the "Technical Clarity" needed to help our clients distinguish between construction-grade and premium-industrial-grade oxides, ensuring the highest performance at the best price point.
Comparison Usage Areas
- Product R&D: Comparing grades for new paint or plastic formulations.
- Procurement Optimization: Selecting the most cost-effective grade for specific tasks.
- Quality Control: Establishing benchmarks for incoming material inspections.
- Technical Training: Educating staff on the differences between synthetic and natural oxides.
Comparison Metric Examples
| Property | Economy Grade | Premium Grade |
| Iron Content | 85% - 90% | 95% - 99% |
| ΔE Tolerance | < 1.5 | < 0.5 |
| Oil Absorption | Standard | Precision Controlled |
| Heat Stability | Up to 180∘C | Up to 800∘C (101) |
| Hiding Power | Good | Superior |
Core Characteristics of Grade Selection
- Performance Mapping: Choosing the pigment based on the final environment (e.g., UV, Acid, Heat).
- Economic Analysis: Balancing high tinting strength against price per kilogram.
- Processing Compatibility: Matching particle size to the dispersing equipment (HSD vs. Ball Mill).
- Purity Requirements: Selecting low-impurity grades for specialized chemical or cosmetic use.
Q: Why is Red 101 more expensive than Red 130?
A: Red 101 is a calcined grade requiring more energy and providing higher purity and heat stability.
Q: Can I use an "Industrial Grade" for concrete?
A: Generally yes, but industrial grades for paints may be more finely ground than necessary for masonry, increasing your cost without benefit.
Technical Consultation Services
We offer "Grade Substitution Audits," where we analyze your current pigment usage and suggest a more efficient or cost-effective Demi grade.
Sample Comparison Kits: We can provide a kit containing various grades of the same color for your lab to test in-house.
The Science of Morphological Distinction
In grade comparison, the "Microscopic Difference" is often the most important. For example, precipitated Yellow Oxide (α-FeOOH) is needle-shaped (Acicular), while calcined Red Oxide (α-Fe2O3) is spherical. This scientific difference affects "Viscosity," "Flow," and "Weathering." Understanding how particle shape influences the "Packing Fraction" in a coating is the key to professional pigment selection, allowing you to optimize everything from the dry-time to the final gloss of your product.
