Abstract

본 발명은 수분경화형 우레탄 실란트의 제조방법에 관한 것으로서, 더욱 상세하게는 폴리올과 폴리이소시아네이트 등으로 이루어진 프레폴리에 신규한 촉매 등을 사용하여 제조함으로써 수분이 없는 경우에서는 저장 안정성이 우수하고, 수분과 접촉할 때는 신속하게 경화됨으로써, 건축, 컨테이너 또는 자동차 등의 소재로서 유용하게 사용될 수 있는 수분경화형 우레탄 실란트의 제조방법에 관한 것이다.The present invention relates to a method for producing a water-curable urethane sealant, and more particularly, by using a novel catalyst or the like in a prepoly composed of a polyol and a polyisocyanate. The present invention relates to a method for producing a water-curable urethane sealant that can be used as a material for construction, containers, automobiles, and the like by rapidly curing when contacted.
