A one-component moisture curable polyurethane composition containing a silane adduct is provided. The composition does not suffer from adhesion failure even when curing conditions were changed, and the composition exhibits excellent adhesion to various materials, and in particular, to glass and aluminum with no primer application. The composition also exhibits excellent curability, high foaming resistance, and good elongation. The moisture curable polyurethane composition comprises a urethane prepolymer, and a morpholine catalyst comprising a dimorpholinodiethylether (i) and a N,N-dimethylaminoethylmorpholine (ii). In the polyurethane composition, content of the dimorpholinodiethylether (i) in the polyurethane composition is preferably less than 0.15% by weight, and content of the N,N-dimethylaminoethylmorpholine (ii) in the polyurethane composition is preferably in the range of 0.04 to 2% by weight.
