A Study on The Improvement of Construction Defect of Aftercuring Polyurea Coating Film for Waterproof and Anti-corrosion

후경화 방수방식용 폴리우레아 도막의 하자 개선 방안 연구

In the case of buildings such as a house or building, so when the rainwater penetrates heard, a portion not penetrating into the evaporation to give an adverse effect on the durability of a building structure, the roof construction or the like, an outer wall, using various methods for water / material. The improved heat resistance, yellowing, adhesion strength of the primer in order to improve the durability of a polyurea film in use recently. Was improved as compared to the existing problems in the polyurea film and the study of post-cure the polyurea system. The heat treatment of at least 90% ks f 4922, in moisture curing primer system environment, improved yellowing. We look forward to leveraging the new paradigm of the research plan is the construction site.
