Antifouling paint composition, antifouling coating film, base material with antifouling coating film, and manufacturing method thereof

摘要

One or more selected from curable organopolysiloxane (A) having at least two silanol groups in one molecule, organosilane having at least two hydrolyzable groups in one molecule, and a partially hydrolyzed condensate thereof. From the antifouling coating composition containing the organic silicon cross-linking agent (B) and the curing catalyst (C) containing an alkali metal compound, the kit for preparing the antifouling coating composition, and the antifouling coating composition. The formed antifouling coating, the base material with the antifouling coating, and the manufacturing method thereof. It does not use a tin-based catalyst or a bismas-based catalyst, has rapid curability even in a low temperature environment, and further prevents Provided is an antifouling coating composition having excellent stain resistance.
