PURPOSE:To obtain an underwater antifouling coating agent excellent in storage stability, dryability, adhesion, lubricity and antifouling property, by mixing a specified copolymer with a surface lubricant. CONSTITUTION:An underwater antifouling coating agent of a viscosity at 25 deg.C <=150P is obtained by dissolving 5-80wt.% polymer of a monomer (a) of formula I [wherein X and Y are each H, methyl or a group of formula II (wherein R' is H, alkyl or phenyl), provided that when X is H, Y is a group of formula II, n is 0-5, m is a real number >=0 and R1-5 are each alkyl, alkoxyl, (substituted)phenyl or (substituted)phenoxyl] or copolymer of monomer (a) with 5-95wt.% vinyl polymerizable monomer (b) copolymerizable therewith (e.g., methyl methacrylate) and having a weight-average MW of 1,000-1,500,000 and, optionally, 1-70wt.% surface lubricant (e.g., paraffin wax) in an organic solvent (e.g., xylene).
Silyl (meth) acrylate copolymers, processes for preparing the same, antifouling paint compositions containing the silyl (meth) acrylate copolymers, antifouling coating films formed from the antifouling paint compositions. antifouling methods using the antifouling paint compositions, and hulls or underwater structures coated with the antifouling coating films
