(57) [Summary] In a method for preventing contamination of a substrate in a marine polluted environment, prior to exposure to the environment, a general formula: Wherein W is a group of the general formula -Si (R 1 ) α (OR 2 ) 3 -α (where α = 0, 1 or 2, preferably α = 0, and R 1 and R 2 independently may contain one or more ether groups, have the meaning of aryl or alkyl group of a straight-chain or branched alkyl group of C 1 -C 6, or C 7 -C 12, And preferably R 1 and R 2 are C 1 -C 4 alkyl groups), L is an organic linking group, Y is F or CF 3 , and R f is 350-8000 At least one of the following structures, having a number average molecular weight of preferably 500-3000 and randomly distributed along the chain: Wherein X is F or CF 3 , and R 4 and R 5 independently have the meaning of H, Cl, or C 1 -C 4 perfluoroalkyl. Forming a coating comprising a curable fluorinated resin on a substrate. |
