Abstract
The anticorrosive coating composition of the present invention is characterized by comprising (A) an epoxy resin, (B) an amine curing agent and (C) a hydroxyl group-containing coumarone resin wherein the hydroxyl group-containing coumarone resin (C) is contained in an amount of 1 to 500 parts by weight based on 100 parts by weight of the epoxy resin (A). The hydroxyl group-containing coumarone resin (C) preferably has a hydroxyl group content in one molecule of 1 to 5% and a softening point of not higher than 200° C. The anticorrosive coating composition can form a coating film in which the plural resin components are homogeneously mixed and which are excellent in anticorrosion properties, water resistance and adhesion. Further, since the coating composition is free from tar unlike conventional anticorrosive coating compositions, it can form a clear coating film free from bleeding out of any component, and safety and hygiene problems at the time of coating operation thereof do not occur.
