  • Conductive metallic coating material, method of corrosion prevention with conductive metallic coating material, and method of corrosion-preventive repair therewith
    Patent number: 9290670
    Abstract: Provided is a highly versatile conductive metallic coating material which is free from the limitation related to a facility without handling complication, and which can maintain its anticorrosive action for a long period. Specifically provided is a conductive metallic coating material which has an organic resin component and a metal component containing aluminum and magnesium and which exhibits a sacrificial anticorrosive reaction on iron. A content ratio of the metal component and the organic resin component is desirably 98:2 to 80:20 in terms of weight ratio. The conductive metallic coating material according to the present invention is usable for preventing corrosion of a building structure or a civil engineering structure and for repairing a corrosion proof treated surface of an existing building structure or a civil engineering structure.
