ANTIFOULING PAINT COMPOSITION, COATING FILM MADE FROM THE COMPOSITION, ANTIFOULING METHOD USING THE COMPOSITION, AND HULLS OR SUBMARINE STRUCTURES COVERED WITH THE COATING FILM

摘要

The present invention contains a structural unit derived from at least one of antifouling agents (A), a trialkylsilyl ester of polymerizable unsaturated carboxylic acid selected from the [I] copper, copper compound, zinc pyrithione as the group with 20-65% by weight a number average molecular weight of 1000-50000 in the film forming copolymer (B) and the number average molecular weight of 200-1200 having 8-30 carbon atoms, a chlorine content of 35-75% by weight contaminated with chlorinated paraffin (C), which preventing relates to a coating composition. The amount of the film forming copolymer (B) of the chlorinated paraffin (C) preferably contains 18-65 parts by weight per 100 parts by weight.; In another aspect, the present invention [II] Component (B), and with (C) and zinc white (D) (B) :( D) = 100: relates to 1-1000 contamination-proof paint composition. The invention also relates to a hull or an underwater structure coated with the Clean Air Act and the coating film using a coating film, each of the anti-contamination coating composition formed from each of the contamination-proof paint composition. The compositions [I], [II] the boat floor and peeling resistance and cracking resistance, antifouling property and the consumable (self-gloss) from the primer layer can be formed in an excellent anti-contamination film. In addition, this anti-contamination coating composition is excellent in storage stability.
