Abstract: Provided are a waterproof coating material and a roof having a coating film formed therefrom which have low VOC content, good film curability under low-temperature/high-humidity conditions, high stain resistance, and low water absorbency. The coating material comprises: (A) 100 parts by weight of a polyoxyalkylene polymer (a1) and/or a vinylic polymer (a2), the polymers each containing a reactive silyl group of formula (1): —SiR13-aXa (1) wherein each R1 independently represents a C1-C20 alkyl, C6-C20 aryl, or C7-C20 aralkyl group, or a triorganosiloxy group of (R′)3SiO— where R's each independently represent a C1-C20 substituted or unsubstituted hydrocarbon group; each X independently represents a hydroxy or hydrolyzable group; and a represents 1, 2 or 3; and (B) 0.1-20 parts by weight of at least one compound including a compound (b3) obtained by partial condensation of silyl groups of an aminosilane alone or of a combination of an aminosilane and another alkoxysilane compound.

Abstract: The present invention has its object to provide a liquid-applied moisture-permeable waterproofing material that can protect a building from rainwater or humidity in the air, can drain moisture, which has been gathered on a substrate of a building, and can be applied easily. The present invention is a curable composition comprising: (A) a polyoxyalkylene polymer having a silicon-containing group crosslinkable by forming a siloxane bond; (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: —OR9 (wherein R9 is a substituted or unsubstituted C1-20 hydrocarbon group), and a group represented by the formula: —NR102 (wherein R10 is each independently a hydrogen atom, or a substituted or unsubstituted C1-20 hydrocarbon group).
