The coating matrix is preferably formed of an elastomeric material selected from the group of butyl and natural rubbers, neoprene, polybutylene, polyisoprene, polybutadiene, polysulfides, polyurethanes, vinyls, polyacrylonitriles, and copolymer blends thereof. Selected antifoulants that diffuse through a coating matrix of the abovementioned materials include tributyltin oxide and 2, 4, 5, 6-tetrachloroisophthalonitrile.
