(57) [Summary] [Object] To provide a metal coating composition for anticorrosion which does not elute chromium ions harmful to the environment and does not cause the problem of waste liquid treatment of chromium compounds. [Composition] A vanadium compound is contained in place of the chromium compound, and other main components include zinc powder, aluminum powder, and alloy powders thereof as a sacrificial anode, either alone or as a mixed powder of two or more thereof, as a film-forming aid. A coating composition for metal anticorrosion containing the water-soluble fluoride, glycols and / or celluloses of 1. [Effect] Since the vanadium compound does not elute, it does not adversely affect the environment and can provide a durable anticorrosion coating in a corrosive environment containing a large amount of sulfur dioxide and sea salt particles. |
