Abstract : Development of novel, low-pollution-risk, antifouling organometallic polymers represents an advance in the state-of-the-art antifouling technology and promises to reduce the pollution from antifouling coatings at least tenfold. To date, acrylic, vinyl, styrene, and polyester organometallic polymers have shown excellent resistance to fouling organisms for 19, 17, 9, and 6 months, respectively, during panel immersion at Pearl Harbor Naval Shipyard. During accelerated aging trials, using a rotating cylinder apparatus, organometallic polymers have demonstrated lower leaching rates than conventional shipboard antifouling coatings. A black antifouling paint is being formulated from an organometallic polymethacrylate with air-pollution-exempt solvents, to meet Navy standards. (Author)
