Natural iron oxide red is a red powder pigment, It is made from high quality raw materials. Its main chemical element is Fe2O3, natural iron oxide red owns stable quality, high weather ability, good resistance to anti-aging, anti-rust, acid and alkali.
Resists fading in exterior applications.
Strong color strength reduces required dosage.
Suitable for extrusion and high-temp processing.
Stable inorganic chemistry; suitable for many regulatory environments.
Natural iron oxide red pigment is widely used in paints and coatings, construction materials, anti-corrosion coatings, rubber, glasses, magnetic materials etc.
