The present invention relates to a curing agent for producing a polyurethane, a composition for producing a polyurethane, and a method for producing a polyurethane using the same. According to the present invention, it is possible to provide a novel curing agent that can be easily used at room temperature, does not impair the mechanical properties of a polyurethane elastomer which is the final product, does not generate toxic substances, and has market competitiveness in economic terms. In addition, it is possible to produce a polyurethane excellent in physical properties therefrom. 본 발명은 폴리우레탄 제조용 경화제, 폴리우레탄 제조용 조성물 및 이를 이용하여 폴리우레탄을 제조하는 방법에 관한 것으로서, 본 발명에 따르면, 상온에서 쉽게 사용할 수 있고, 최종 생성물인 폴리우레탄 탄성체의 기계적 물성을 저해하지 않으며, 유독물질을 발생시키지 않고, 경제적인 측면에서도 시장 경쟁성을 가지는 신규한 경화제를 제공할 수 있다. 또한, 이로부터 물성이 우수한 폴리우레탄을 제조할 수 있다.
