COATING COMPOSITION FOR PREVENTING ATTACHMENT OF MARINE ORGANISM, AND METHOD FOR PREVENTING ATTACHMENT OF MARINE ORGANISM

摘要

PPROBLEM TO BE SOLVED: To provide a coating composition for preventing the attachment of marine organisms, preventing the attachment of the ocean organisms to an ocean structure or a ship by applying electric characteristics of garnet causing no marine pollution, and synergistic action of anatase-type titanium dioxide. PSOLUTION: The coating composition for preventing the attachment of the marine organisms is obtained by compounding a mixed fine powder of a mineral-fired oxide containing the garnet and rare earth elements, and the anatase-type titanium dioxide with a synthetic resin compound. When the composition is formed into a coated film, the coated film component is not eluted even when soaked in sea for a long period. The attachment of the ocean organisms is prevented by heightening an alkali ion concentration of water at the surface of the film. PCOPYRIGHT: (C)2006,JPO&NCIPI
