| Abstract: | This high strength polyurethane waterproof coating was composed of two part: A and B, Part A was polyurethane prepolymer which was prepared from polyether polyol and diisocyanate Part B was composed of aromic amine and polyetherdiol. Its stretch strength was 3.0 -10 MPa, stretch length was 200 % -400 % , ad-hisive strength was or more than 2.0 MPa. The waterproof coating was suit for water conservancy construction. |
