Iron oxide pigment
Product category
Introduction:
Iron oxide pigment is a kind of pigment with good dispersibility, excellent light resistance and weather resistance. Iron oxide pigment mainly refers to four types of coloring pigments with iron oxide as the basic substance, namely iron oxide red, iron yellow, iron black and iron brown. Among them, iron oxide red is the main one (accounting for about 50% of iron oxide pigments). Iron oxide is the second largest inorganic pigment after titanium dioxide and the largest colored inorganic pigment.
