Abstract
Copper flake is treated to remove oxides and other contaminants from its surface and incorporated into an uncured water-insoluble polymer. When applied to a marine structure such as a boat hull, the coating exhibits outstanding anti-fouling properties. The cleaned copper flake is preferably incorporated into an uncured epoxy resin modified by reaction with a polyol. In one embodiment of the invention, the coating is applied and cured underwater using a strippable carrier.
