Joint Reinforcing Coatings for Navy Ships CRES Pipe Systrms

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.
