Copper Based Antifouling Paints for Prevention of Marine Growth on ship Hulls
Keywords: Chlorinated paraffin, Rubber rosin, Cuprous oxide, Antifouling
Abstract"The mode of action and requirements of ingredients of copper based antifouling paints used in the country for the prevention of fouling, on ship-hulls have been described. The studies on performance of antifouling paints based on cuprous oxide-chlorinated rubber-rosin system have also been reported. Antifouling life improves with increase in concentration of cuprous oxide, 43 per cent by volume being the optimum toxic content. A minimum rosin to resin ratio of 3:1 is required to permit adequate release of copper for prolonged periods. Hydrolysable plasticizer namely tricresyl phosphate has been found to be superior to chlorinated paraffin wax for the design of antifouling compositions. The antifouling paint based on chlorinated rubber resin is expected to give a life of 15-18 months in service."
