Patent ID: 8354168

Claim:
An organopolysiloxane antifouling composite coating film comprising: (I) an anticorrosive coating film; and (II) an organopolysiloxane antifouling coating film, wherein the anticorrosive coating film (I) and the organopolysiloxane antifouling coating film (II) are laminated in order on a surface of a base, wherein the anticorrosive coating film (I) is formed from an epoxy anticorrosive coating composition comprising: (A) an epoxy resin; (B) a curing agent for epoxy resins; and (C) a modifier, which is either (i) a modifier comprising a hydroxyl group-containing petroleum resin (c1), or (ii) a modifier comprising a hydroxyl group-containing petroleum resin (c1) and a coumarone resin (c3), and wherein the organopolysiloxane antifouling coating film (II) is formed from a moisture-curing organopolysiloxane composition comprising an organopolysiloxane represented by the following formula (II) having a condensing functional group at both ends of a molecule: wherein W is a hydroxyl group or a hydrolyzable group, R 1 and R are each independently represented by a substituted or unsubstituted monovalent hydrocarbon group having 1 to 12 carbon atoms, with the proviso that a plural of R 1 and a plural of R may be the same or different, n is an integer of 5 or greater, and a is 0, 1 or 2, and wherein the hydroxyl group-containing petroleum resin (c1) has 1 to 2 hydroxyl groups in one molecule.
