  • Publication number: 20130224496
    Abstract: The present invention is directed to the surprising discovery that a hard, low energy epoxysilicone/organic epoxy coating can be generated that can be easily sanded, easily repaired and are chemically stable to the marine environment. The invention reveals the use of epoxy functional siloxanes that chemically bond with an organic epoxy polymer and a polyfunctional amine or amide to form block copolymer networks with the silicone distributed through the entire matrix. The coating thus generated can be applied directly over most hull substrates, anticorrosion coatings or as a repair over itself.
