| abstract |
The present application discloses a self-polishing antifouling coating composition comprising a) a base component comprising a pre-polymer which i) has alkoxysilyl-functional group(s) and/or ii) is curable in the presence of a curing agent/catalyst, and have side chain(s) bearing terminal group(s) of the formula I -X-O-(SiR 1 R 2 O) n -SiR 3 R 4 R 5 , wherein X is >C=O, n is 0-5,000,and R 1 , R 2 , R 3 , R 4 and R 5 are selected from C 1-20 -alkyl and optionally substituted phenyl;and b) a curing agent/catalyst. The application also discloses i) a corresponding kit comprising the antifouling paint composition, wherein a first container holds the base component and a second container holds component b;ii) a corresponding base component for an antifouling paint composition comprising a hydroxy-functional pre-polymer having terminal group(s) of the general formula I; iii) a marine structure; and iv) a method of coating a structure. |
