To provide a two-component curing type urethane composition which has excellent storage stability such that it keeps initial work life and coating work efficiency even after it is saved for a long period of time and there is no change in a time required to be cured after the end of work.
The two-component curing type urethane composition comprises: a base component (I) containing an urethane prepolymer (A) obtained by the reaction of a polyisocyanate with a polyoxy alkylene polyol and having two or more isocyanate groups at the terminals and an urethan compound (B) having an oxazolidine at the terminals; and a curing agent (II) containing a retarder (C) comprising an organic acid calcium and a water-in-oil type emulsion (D), wherein the water content of (D) is 0.1-1.5 wt.% in the two-part curing type urethane composition comprising (A), (B), (C) and (D).
