Abstract:
1. A moisture-permeable waterproofing material for a building comprising a cured product obtained by curing a curable composition comprising: (A) a polyoxyalkylene polymer having a silicon-containing group crosslinkable by forming a siloxane bond which is selected from a group consisting of —CH wherein the polyoxyalkylene polymer is a polyoxypropylene polymer; (B) a polyoxyalkylene plasticizer whose main chain contains 5 wt % or more of an oxypropylene-derived repeating unit and has one or more groups, at an end thereof, selected from the group consisting of an —OH group, a group represented by the formula (7): (wherein R and a group represented by the formula (8): (wherein R said curable composition being liquid and being a curable composition wherein the component (B) is a polyoxyalkylene plasticizer (B1) that does not have an —NH wherein a ratio (W2/W1) of a total weight (W2) of the component (A) and the component (B1) with respect to a total weight of the curable composition (W1) is 53 to 78 wt %, and wherein moisture permeability according to ASTM E96 (wet cup method) of said cured product is 0.6 perm·inch or more.
