In a monocomponent moisture-curable polyurethane resin composition, a facile catalytic compound is used to improve two repellent properties of curing capability and storage stability more proportionally and adequately. The monocomponent moisture-curable polyurethane resin composition contains, as essential components, a prepolymer of isocyanate terminal ammine ester deriving from polyoxyalkylidene polyalcohol and organic diisocyanate, and a curing catalyst: N-alkyl morpholine (C6-24 alkyl, preferably N-cocoporpholine). |
