Joint Reinforcing Coatings for Navy Ships CRES Pipe Systrms Navy SBIR FY2015.1 Sol No.: Navy SBIR FY2015.1 Topic No.: N151-042 Topic Title: Joint Reinforcing Coatings for Navy Ships CRES Pipe Systrms Proposal No.: N151-042-0458 Firm: Resodyn Corporation 130 North Main Street Suite 600 Butte, Montana 59701 Contact: Eduard Stefanescu Phone: (406) 497-5227 Web Site: www.resodyn.com Abstract: The U.S. Navy seeks a proactive approach to reinforce the thin walled corrosion resistant steel (CRES) pipes at the welded joints in order to prevent potential leaks from occurring in situations where joint cracks are generated. Currently, there is no known product available to meet this need. Resodyn Corporation proposes for development a clear, tough, corrosion protective, VOC-free thermoplastic, joint reinforcement coating (JRC) to address the U.S. Navy's need under consideration. The JRC will be capable to strongly adhere to CRES substrates, and will be sprayable in hard-to-reach, confined spaces. The clear thermoplastic component will be primarily based on a strong and affordable thermoplastic polyurethane (TPU) characterized by excellent chemical resistance to hydrocarbon fluids such as JP-5, transmission fluids, motor oils, etc. The resin will be further reinforced with cutting edge anisotropic fillers in amounts that will not hurt transparency. The JRC's "see through" nature will offer the possibility to non-destructively inspect the joint welds periodically through a visual examination. Resodyn Corporation's patented Polymer Thermal Spray (PTS) technology will be employed to deposit the resultant JRC materials starting from precursor materials in the solid state, powdery form. The PTS technology also allows for coating repairment in short periods of time. Benefits: Resodyn Corporation's novel thermoplastic polymer solution will provide U.S. Navy ships with a robust, proactive approach to reinforce the thin walled corrosion resistant steel pipes at the welded joints, and in doing so will primarily increase the likelihood of success of missions involving such ships. The solution would increase mission capability in that the U.S. Navy's ships will stay mission-ready for greater periods of time in between docking periods. In addition, the solution proposed by Resodyn Corporation will provide peace of mind, knowing that the U.S. Navy's ships will be able to approach targets without fear of unforeseen critical failures of the fuel piping system. The transparency of the joint-protective coating represents an important feature that will enable U.S. Navy personnel to periodically inspect each joint-weld and to evaluate the overall condition of the piping system, which in turn will allow them to make early, informed decisions regarding repairment and/or down-time vs. deployment schedules. Last but not least, a key advantage of this technology is the possibility of applying the material in hard-to-reach areas, which ultimately translates into an applicator-friendly process that allows for an effective coating of welded joints with a reasonable amount of training and effort.
