CURABLE ORGANOPOLYSILOXANE ANTI-FOULING COMPOSITE COATING, AND ANTI-FOULING SUBSTRATE COATED WITH THE COMPOSITE COATING

摘要

The present invention relates to an organopolysiloxane antifouling film excellent in both interlayer adhesion and antifouling performance to the anticorrosive coating film by using a urethane resin type coating film having excellent curability in place of the one or two layered organopolysiloxane intermediate coat film (Tie Coat) And a cured organopolysiloxane-based antifouling composite coating film obtained by laminating the composite coating film and an antifouling substrate coated with the composite coating film. In order to solve the above-mentioned problems, the antifouling composite coating film of the present invention comprises: (I) a urethane resin type coating film formed from a anticorrosive coating composition comprising a subject and an isocyanate-based curing agent selected from the group consisting of polyols and glycidyl ethers; (II) an antifouling coating film formed of a curable polysiloxane composition containing specific components (a), (b) and (c).
