Abstract:
An article comprising a marine structure coated with an anti-fouling coating which is the reaction product of a condensation curable coating composition comprising the following:(A) a room temperature vulcanizable polyorganosiloxane composition comprising at least one reactive silicone, at least one condensation catalyst and at least one crosslinking agent, the reactive silicone being a polydialkylsiloxane having the formula: wherein each R1 is a hydroxyl radical or wherein each R2 is independently a hydrocarbon or fluorinated hydrocarbon radical, each R3 and R4 is a hydrocarbon radical, a is 0 or 1 and m has a value such that the viscosity of said reactive silicone under ambient temperature and pressure conditions is up to about 6,000 centipoise; and(B) about 5-20 parts by weight, per 100 parts of component A, of at least one organic compatible silicone fluid capable of blooming to the surface of the cured product of component A, said silicone fluid having the formula where n varies from 1 to 8000 and R5 is selected from the class consisting of from lower alkyl radicals of 1 to 20 carbon atoms, substituted alkyl radicals of 6 to 20 carbon atoms and aryloxyalkyl radicals of 7 to 50 carbon atoms, about 2 to 100 mole % of the R5 radicals being C6-20 alkyl radicals or substituted aryl-alkyl radicals.
