Conductive coating material for preventing adhesion of marine organism

TLDR: In this article, the authors proposed a method to obtain the title coating material which is excellent in resistance to electrolysis by seawater and can maintain the effect of preventing the adhesion of marine organisms over a wide area for a long period of time, by using a specified copolymer resin, a conductive filler and a solvent as the constituents.

Abstract: PURPOSE:To obtain the title coating material which is excellent in resistance to electrolysis by seawater and can maintain the effect of preventing the adhesion of marine organisms over a wide area for a long period of time, by using a binder comprising a specified copolymer resin, a conductive filler and a solvent as the constituents. CONSTITUTION:The title coating material contains: a binder comprising a copolymer resin which consists at least of 80-98.5wt.% methyl methacrylate component, 1-15wt.% of at least one monomer component selected from among (meth)acrylic esters (except methyl methacrylate) (e.g. butyl methacrylate), and 0.5-5wt.% of at least one monomer component selected from among an unsaturated dicarboxylic acid, a phosphoric ester, a sulphonic ester, an aminated vinyl monomer and an epoxidized vinyl monomer (e.g. maleic anhydride), the total of these components accounting for at least 90wt.% of the copolymer; a conductive filler (e.g. graphite powder); and a solvent (e.g. toluene and methyl isobutyl ketone).
