ABSTRACT: A polymeric composition containing copper flake in sufficient quantities to render the entire thickness of the polymeric composition electrically conductive. The copper flake is treated to remove oxides and reacted with conven- tional epoxy resins modified with an expoxidized polyol (polyglycol). The formulation not only exhibits outstanding antifouling properties but also exhibits antisliming prop- erties. The composition is useful as a coating material and when utilized on ships, boats, and other water craft, a vessel results which requires no additional antifouling or antisliming treatment for several years. The composition can also be used to great advantage as a liner for pipes and conduits used to transport salt or fresh water where fouling of the pipes is a problem. In one embodiment of the invention, a composition is disclosed which will cure under water. This particular formulation can be used to great advantage in patching holes in copper clad hulls and the like while the vessel is in water.
