ABSTRACT:
An epoxy composition for application to the surface of a marine vessel. The epoxy composition comprises an epoxy resin and an iron particulate combined with one or more materials, preferably dry materials, which are piped into a feeder and then into a mixer. The dry materials are selected from a group of one or more additives comprising a ceramic material, an amorphous fumed silica such as Cab-O-Sil®, a silicone and a color pigment. The combined mixture is then submitted to a polarizing process so that the iron particulate is magnetized to create a polarized, electromagnetic field.A second mixture comprising an epoxy hardener, a ceramic material and an amorphous fumed silica is produced for ultimately combining with the epoxy resin mixture at the point of application to the marine vessel.
