摘要

The composition of the coating with high solid content of healing environment, process to prepare a coating composition with high solid content of healing environment, process to prepare a coated substrate and article coated.The present invention relates to a composition for coating with high solid content of healing environment.Comprising: (a) an epoxy resin; (b) a block copolymer containing at least one segment of anfifu00edlico block miscible with epoxy resin and at least one segment of the block immiscible with epoxy resin; and the segment of immiscible block comprises at least a structure of poliu00e9te R; such that when the composition of epoxy resin is cured.The tenacity of epoxy resin composition cured result is increased; and (c) a sufficient amount of curing agent containing nitrogen to cure the coating composition to a temperature of less than 60 u00b0 C.The block copolymer anfifu00edlico is preferably a block copolymer, entirely of polyether as a copolymer in dibloco peo - PbO or a triblock copolymer of peo - PbO peo.
