    摘要: An antifouling coating composition includes (A) antifouling agent, (B) film forming copolymer of 1000 to 50,000 in number average molecular weight, and structural units derived from a trialkylsilyl ester of polymerizable unsaturated carboxylic acid in an amount of 20 to 65% by weight, and (C) chlorinated paraffin. The composition may also contain one or more of (D) (meth)acrylic ester polymer of 1000 to 100,000 in number average molecular weight; (E) inorganic dehydrating agent, (F) flake pigment, (G) zinc flower. In other embodiments the composition includes above components (A), (B) and (D) wherein (B):(D)=100:10 to 500. Coating films formed from the above antifouling coating compositions, such as on a hull or an underwater structure, are excellent in cracking resistance, resistance to peeling from ship bottom materials and primer layers, antifouling properties and consumability (self-polishing properties). Further, these antifouling coating compositions are excellent in storage stability.
