Iron oxide pigment have many colors, from yellow to red, brown to black. Iron oxide red is a kind of iron oxide pigment. It has good hiding power and tinting power, chemical resistance, color retention, dispersibility, and low price. Iron oxide red is used in the production of floor paints and marine paints. Because of its remarkable anti-rust performance, it is also the main raw material for making anti-rust paints and primers. When the iron oxide red particles are ground to ≤0.01μm, the hiding power of the pigment in the organic medium will be significantly reduced. This kind of pigment is called transparent iron oxide, which is used to make transparent colored paint or metallic flash paint,。The effect is better than the color retention of organic pigments.
