Iron Oxide Red 895 Cement Concrete Blocks Tiles Bricks Stamped Concrete Pigment of Ferric Oxide (Fe2O3) for Coating Use

Iron oxide red /yellow/black/green/brown/blue/green
Varied hues of color in line with many specifications, fine bright red powder though in a variety of specifications. Better dispersion. Strong covering power and tinctorial strength, a specific gravity of about 5.1, and average particle size < 1 micron. Small water absorption, good penetrability for ultraviolet ray, more stable in the atmosphere and under the sunlight, good light-fastness, heat and good alkali resistance, only soluble in the hot strong acid.
Addition compound of ferrous oxide and ferric oxide , with magnetism, high strength and covering power, good resistance to light and atmosphere, good light-fastness, and no impermeability or oil residue. It is very stable in general organic solvents, not resistant to acid, soluble in hot strong acid. Good alkali resistance.
