Abstract:
1. An epoxy resin coating composition which comprises, at least, epoxy resin, a thiol-type curing agent and a curing assistant, being composed of a mixture of two liquids of liquid (A) containing epoxy resin, a thiol-type curing agent and an aprotic volatile solvent and liquid (B) containing a curing assistant, which liquids are mixed just before using, wherein the thiol-type curing agent contains a branched compound containing a thiol group (P), which compound is an ester of polyhydric alcohol with secondary thiol group- or tertiary thiol group-containing carboxylic acid represented by formula (1) wherein R 1 represents a hydrogen atom or a linear or branched alkyl group having 1 to 10 carbon atoms, R 2 represents a linear or branched alkyl group having 1 to 10 carbon atoms, and n represents an integer of 1 to 4, wherein the epoxy resin coating composition does not contain a protic solvent, wherein the content of the thiol-type curing agent is 35 to 82 parts by mass based on 100 parts by mass of epoxy resin, and the content of the curing assistant is 0.1 to 20 parts by mass based on 100 parts by mass of the epoxy resin coating composition.
