Product Details
Comprehensive information about our iron oxide pigments including specifications, applications, advantages, and more
Protective Paint Grade Iron Oxide
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
Engineering Longevity into Industrial Coatings
Deqing Demi Pigment Technology Co., Ltd. is a specialized manufacturer of high-purity oxides for the global protective coatings industry. We understand that in industrial maintenance, the cost of failure is astronomical. Our protective-grade series is engineered to provide the "First Line of Defense" for ships, bridges, and oil rigs. By controlling the purity of our iron oxide at the molecular level, we ensure that our pigments enhance the anti-corrosive performance of every primer and topcoat they are integrated into.
Protective Grade Usage Areas
- Marine Primers: High-purity red oxides for ship hulls and ballast tanks.
- Bridge Coatings: UV-stable protective layers for structural steel.
- Pipe Linings: Chemical-resistant colorants for oil and gas pipelines.
- Chassis Paints: Durable, impact-resistant finishes for heavy machinery.
Protective Grade Technical Specs
| Metric | Value | Standard |

| Chloride Content | Max 0.005% | ISO 787-13 |
| Hegman Fineness | 6.0 - 7.0 | ISO 1524 |
| Sulphate Content | Max 0.01% | ISO 787-13 |
| Density | 5.0 - 5.2 g/cm³ | ISO 787-10 |
Core Advantages
- Corrosion Inhibition: Passivates the metal surface to stop rust before it starts.
- Exceptional Adhesion: Promotes a stronger bond between the resin and the metal.
- Thermal Resistance: Maintains stability in high-heat industrial processes.
- High Volume Loading: Low oil absorption allows for thick-film application.
Q: Why is low chloride content important for metal primers?
A: Chlorides act as catalysts for rust. Our pigments are washed multiple times to ensure they don't introduce salt to the metal surface.
Q: Can this be used in Epoxy systems?
A: Yes, our protective grade is highly compatible with two-component epoxy and polyurethane systems.
Corrosion Resistance Testing
We offer "Salt Spray Testing" data for our pigments in various resin systems, providing proof of performance for 500, 1000, and 2000-hour exposure cycles.
Micro-milled Protection: For thin-film industrial coatings, we provide micronized versions that ensure a smooth finish without compromising the anti-corrosive barrier.
The Science of Barrier Protection
In protective coatings, we focus on the "Tortuous Path." By providing a high concentration of dense, crystalline iron oxide particles, we force moisture and oxygen molecules to navigate a long, winding path to reach the metal substrate. This significantly slows down the diffusion rate. We measure the "Particle Aspect Ratio" to ensure the pigments pack tightly within the cured film, creating a nearly impermeable shield against the elements.
