ABSTRACT:
A marine antifouling coating composition comprises an acrylic resin such as methyl methacrylate in the range of from 6 to 20% by weight, a polysiloxane having substituted thereon tributyltin moieties that are toxic to marine organisms. The polysiloxane is in the range of from 7 to 25% by weight. The acrylic resin and polysiloxane are dissolved in a solvent in the range of from 18 to 52% by weight with the balance of the composition in the range of from 10 to 65% by weight being primarily conventional marine paint and toxicant agents for augmenting action of the tributyltin polysiloxane. Copper or copper salts that are effective for inhibiting growth of marine organisms and facilitating release of toxins can also be included.
