A cathodic protection polymeric compound is disclosed. The compound has
flowable material to serve as a binder, carbonaceous conductive media
dispersed in the flowable material, sacrificial metal particles also
dispersed in the flowable material. The carbonaceous conductive media
serve as a carbon-based electron transfer agent and are in the form of
particles, platelets, fibers, tubes, or combinations thereof. A galvanic
circuit is formed by the metal particles serving as anodes, a metal
substrate to be protected serving as the cathode, and the conductive
media serving as the electron transfer agent. The flowable material can
also include an ionically conductive or an inherently conductive polymer
to further enhance the galvanic circuit.
