LOW-COST, EASILY APPLIED VOC-FREE HYBRIDSIL CRES PIPE LEAK REPAIRING RESINS

Through the proposed NAVY SBIR program, NanoSonic will create and qualify a low-cost, easily applied VOC-free HybridSil CRES pipe leak repairing resin that will readily seal pressurized leaking pipes and prevent crevice corrosion on in-service Aircraft carriers while underway. NanoSonics HybridSil CRES leak repairing material will build from NanoSonics anticorrosion coating technology which has undergone extensive corrosion qualification, demonstrated exceptional solvent resistance to JP-5 fuel, has self-cleaning characteristics within actual marine environments, strong adhesion to metallic substrates without the need for extensive surface preparation or primers and is currently undergoing sea trials on a U.S. Navy vessel. Of particular importance for interior integration, HybridSil has exceptional fire resistance and is certified as a fire restrictive material per the IMO. Building from this technical foundation, NanoSonic will adapt its HybridSil Anticorrosion coating technology to serve as a VOC-free, welded joint leak sealant that will cure within seconds of deposition to stop existing leaks while also affording the environmental durability necessary to last as long as the base piping installation. A rigorous statistical design of experiments will be employed to down-select Phase I nanocomposites. Transition success is ensured through multiple Phase III transition partners and an established pilot scale HybridSil manufacturing infrastructure.
