PROBLEM TO BE SOLVED: To provide a material satisfying a high strength shape at test temperature of 23°C and 60°C defined in urethane rubber tensile performance in JISA6021:2011 "Table 1-performance of coating film water proof material for roof" (hereafter abbreviated to "high strength shape standard"), and capable of processing a covering material such as a water-proof material simply without using an operation by a large machine.SOLUTION: There is provided a moisture-curable urethane composition containing an urethane polymer (A) having an isocyanate group obtained by reacting polyol (a-1) containing polytetramethylene glycol (a-1-1) and chain extender (a-1-2) and polyisocyanate (a-2), an urethane compound (B) having an oxazolidine group and an acid catalyst (C), with used amount of the polytetramethylene glycol (a-1-1) in a specific range.SELECTED DRAWING: None |
