Product Description

Iron Oxide

Product Description

Iron Oxide Black (chemical formula Fe₃O₄) is a synthetic inorganic pigment renowned for its exceptional opacity, weather resistance, and electrical conductivity. It is manufactured via high-temperature calcination and is widely used in coatings, construction materials, electronics, magnetic composites, and inks. Our product delivers cost-effective, high-performance black coloration and functional enhancements for industrial applications.


Key Features 

1.Superior Performance 

1. High Tinting Strength: Deep, pure black coloration with ≥98% opacity (ISO 6504), reducing material usage by 20-30%
2. High Weather Fastness: Heat-stable, UV-resistant, and acid/alkali-proof for harsh outdoor/industrial use.

2. Safety & Certifications  

Non-Toxic: Compliant with RoHS, REACH, EN 71-3 (toy safety), with undetectable heavy metals 

Zero VOC Emissions: Free of volatile organic compounds, certified by GB/T 23986-2009 for eco-friendly indoor coatings.

3. Cost Efficiency  

Multi-Functional: Combines coloration with functionalities (e.g., anti-static, EMI shielding), reducing additive costs.

Batch Consistency: Automated production ensures color deviation ΔE <0.7 (CIE Lab), minimizing production waste.
