摘要：PURPOSE:To prevent the outside plating such as hull and the like from being stained due to the adhesion of aquatic organisms thereonto by a method wherein copper or copper alloy powder is expod above the surface layer of coating at all times by underwater grinding. CONSTITUTION:Coating material consisting in mixing copper or copper alloy powder with epoxy resin, polyester resin and urethane resin, all of which have poor hydrophile property and at the same time to all of which no rosin or the like is added, is coated onto a hull. The initial stain proofing is performed by the eluation of copper ions from the pigments expod above the surface layer of coating. At the point of time when the stain proofing effect starts to decrea, underwater grinding is executed so as to expo the copper or copper alloy powder above the surface layer in order to keep on proofing stain. Long term stain proofing effect is obtained by repeating the above-mentioned coating and underwater grinding.
