Cryogenic adhesives are used to transport and store LNG (Liquid Natural Gas) and LH2 (Liquid Hydrogen) at temperatures between 4 and 103 K.1 The most economical cargo containment system for LNG carriers is the Membrane Type. 2 It has a double structure that forms the primary and secondary barriers by attaching insulation and metal membranes to the inside of the cargo hold. 3 In this study, a method for evaluating physical properties at cryogenic temperatures was established for future localization of urethane adhesives and the curing behavior of two-component urethane adhesives according to curing conditions and physical properties at cryogenic temperatures were evaluated.
