Abstract
A modular antifouling tile is formed with a plurality of reservoirs that contain antifoulant which diffuses therefrom through the matrix of the coating. 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.
