Through its NAVSEA SBIR program, NanoSonic has designed, synthesized, and empirically validated an innovative low-cost, easily applied VOC-free HybridSil CRES pipe leak repairing resin that readily seals pressurized CRES pipes, withstands continuous pipe pressures beyond 350 psi within JP-5 fuel, and prevents crevice corrosion during ASTM B117 salt fog corrosion testing. To meet this challenge, NanoSonic molecularly engineered its state-of-the-art anticorrosion coating technology for 1) exceptional adhesion to CRES 316 L pipes without the need for extensive, time consuming surface preparation, 2) rapidly repairing damaged CRES weld joints (defects between 1/8 to 1? in length) within 15-minute of resin activation, 3) withstanding extended pressurization at 350 psi within JP-5 filled CRES pipes, and 4) facile deposition techniques for repairing damaged pipe areas within very limited work space. NanoSonic?s Phase I down-selected HybridSil CRES pipe repairing material has also demonstrated complete dimensional stability after more than 4-months of JP-5 submersion. Equally important, Fourier transform infrared spectroscopy of the > 4-month exposed JP-5 fuel reveals no spectroscopic evidence of contamination. The extreme environmental durability of NanoSonic?s CRES pipe repairing material has been demonstrated through abrasion analysis (ASTM D4060), mechanical testing (ASTM D 638), and salt fog corrosion exposure (ASTM B117).
