An inorganic high anti-corrosive coating agent is provided to realize excellent resistance against generation of white and red/green rust, and to ensure high quality in welding, so that the coating agent is useful for iron steel structures including various ships. An inorganic high anti-corrosive coating agent having excellent weldability comprises: a pigment formed of mixed powder containing zinc powder(3), aluminum powder(1) and iron phosphate powder(2); and an inorganic silicate(4) as a solvent. The zinc powder, aluminum powder and iron phosphate powder are used in a weight ratio of 1:0.2-0.6:0.1-0.5. The zinc powder has an average size of 2-7 micrometers, the aluminum powder has an average size of 40 micrometers or less, and the iron phosphate powder has an average size of 10-40 micrometers. The pigment and the solvent are used in a ratio of 85:15-95:5 on the dry coating film basis. |
