Micaceous iron oxide gray is a gray powder pigment, it owns high fastness to light, heat and weather, good anti-corrosion resistance, it doesn't change colors even at 1000℃. Micaceous iron oxide gray is recommended for anti-corrosion paints and coatings. The content of Fe2O3 available is 85%, 90%, 93% and 95%, fineness is 60-800mesh accordingly. Furthermore, we can produce micaceous iron oxide red according to customers' standard samples.
Micaceous iron oxide gray’s main content is α- Fe2O3, the crystal is sheet or plate like hexagonal, it is a large radius to thickness ratio, with diameter from tens of microns to a hundred microns, thickness from a few microns to tens of microns. Mohs hardness of micaceous iron oxide gray is 5.5-6.5, it has good light resistance, heat resistance, weather resistance, and excellent rust resistance, micaceous iron oxide gray does not change colors even at 1000°C.
Micaceous iron oxide gray is mainly used in primer, intermediate paint and finish paints of anti-corrosion paints. As well as anti-rust fillers of adhesives and sealants.
