Adopts high-purity sulfuric acid production technology with iron oxide content exceeding 98.5%, boosting tinting strength by 15% compared to ordinary iron oxide red, reducing pigment dosage and lowering coating costs. Its strictly controlled particle size distribution ensures excellent dispersibility in coatings, eliminating caking and flocculation. It has passed 5000 hours of artificial accelerated aging testing, meeting international top-level coating standards for weather resistance, ensuring no obvious fading after 10 years of outdoor use. With low volatile content and neutral pH value, it fits various environmentally friendly coating formulas and complies with EU REACH regulations, providing a stable and reliable red coloring solution for coating manufacturers.
It appears as fine orange-red powder, with iron oxide (Fe₂O₃) content ≥98.5%, average particle size of 0.7-0.9μm, bulk density of 0.8-0.9g/cm³, oil absorption of 27-33g/100g, pH value of 7.0-8.5, volatile matter ≤0.5%, light fastness level 8 per ISO standard, and weather resistance showing no obvious color difference after 5000 hours of ASTM G154 testing. It is packaged in 25kg waterproof Kraft paper bags with PE liners, and 1000kg big bag customization is available for large orders.
It is mainly used in water-based interior and exterior wall latex paint, oil-based acrylic coating, epoxy floor paint, heavy-duty anti-corrosion steel structure coating and other scenarios. It fits home decoration building materials, commercial building painting, industrial plant anti-corrosion and other projects, and can be used as a main coloring agent or color adjustment auxiliary to provide pure and rich red tones for various coatings, especially suitable for outdoor painting projects with high requirements for weather resistance and color stability.
