    摘要: Moisture-curable urethane resin compositions comprising: (a) a urethane prepolymer having two or more terminal isocyanate groups, (b) a blocked amine compound which is essentially nonreactive with an isocyanate group and generates a primary or a secondary amino group upon contact with water, and (c) an inorganic filler treated with an organic compound, are disclosed. More particularly, the urethane resin compositions comprise a hydrophilic urethane prepolymer having oxyethylene moieties, and a blocked amine compound having two or more oxazolidine rings.
