Patent ID: 8574719

Claim:
An anti-fouling coating composition comprising a solution of a solvent, a curable polymer and a fluid organosilicone polymer represented by the general formula: wherein: R1 may be the same or different and is selected from alkyl, aryl, and alkenyl groups, an oxygen-containing group of the formula OR 5 , wherein R 5 is hydrogen or a C 1-6 alkyl, and a functional group according to the formula (I): —R 6 —N(R 7 )—C(O)—R 8 —C(O)—XR 9 (I) wherein R 6 is selected from alkyl, hydroxyalkyl, carboxyalkyl of 1 to 12 carbon atoms, and polyoxyalkylene of up to 10 carbon atoms; R 7 is selected from hydrogen, alkyl, hydroxyalkyl, carboxyalkyl of 1 to 6 carbon atoms, and polyoxyalkylene of 1 to 10 carbon atoms; R 7 may be bonded to R 8 to form a ring; R 8 is an alkylene group with 1-20 carbon atoms; R 9 is hydrogen or an alkyl group with 1-10 carbon atoms, optionally substituted with oxygen- or nitrogen-containing groups; X is selected from O, S, and NH; wherein at least one R1-group in the organosilicone polymer is a functional group according to the above formula (I) or a salt derivative thereof; R2 may be the same or different and is selected from alkyl, aryl, and alkenyl; R3 and R4, which may be the same or different, are selected from alkyl, aryl, capped or uncapped polyoxyalkylene, alkaryl, aralkylene, and alkenyl; a is an integer from 0 to 50,000; and b is an integer from 0 to 100; and a+b is at least 25, wherein the solid content of the coating composition is at least 50 wt %.
