A composition comprises a leachable organic compound distributed throughout a polymer matrix formed by reacting a fluoroepoxy compound of the formula wherein x is an integer from 0 to 12, with a silicone amine curing agent of the formula where n is the average degree of polymerization of the silicone amine curing agent and is 1 or greater. The leaching rate of the leachable organic compound is controlled by selecting the value of x in the fluoroepoxy compound and the value of n in the silicone amine curing agent. The composition may be used as a coating for protecting underwater substrates from fouling by marine organisms.
