Antifouling(AF) efficiency of a nontoxic aliphatic ester, ethyl heptanoate was evaluated against spores of a fouling alga, Ulva pertusa and a ship fouling diatom Amphora coffeaeformis. Based on the nontoxic AF activity exhibited in the laboratory bioassay, a hybrid Controlled Depletion Paint(CDP) formulation was prepared with ethyl heptanoate using acryl resin as a functional binder. To increase its performance, coatings were also prepared in combination with a booster biocide, zinc pyrithione(ZPT). Test panel studies were conducted with newly prepared hybrid CDP-AF coatings(ethyl heptanoate 10-40%) at Ayajin harbor, east coast of Korea from April 2005-May 2006. According to the fouling resistance recorded after 4, 8, and 13 months from the coatings, AF performance of the newly prepared hybrid CDP coatings are discussed.
