Anti-corrosive pigment and anti-corrosive aqueous paint

摘要

An anti-corrosive pigment comprises an ion oxide-calcium oxide sintered composite of an average particle size in a range of 0.7-7 mu m, which contains at least 25% by weight of 2CaO.Fe2O3 and has a extremely low water-solubility of calcium content. An anti-corrosive aqueous paints contains the above pigment and has a superior storage stability without causing a gellation.
