Abstract

Abstract The present invention provides a room temperature-setting composition which is useful for e.g. a sealant, a waterproof agent, an adhesive or a coating agent. The room temperature-setting composition of the present invention is suitable for a use wherein an adequate cohesion of a cured product itself and a dynamic follow up property to the adherend are required, and it is particularly excellent as an elastic adhesive. Further, it is excellent in curing property, particularly in the quick curing property. Therefore, it is useful as the quick curable adhesive or a quick curable sealant. The present invention provides a room temperature-setting composition containing a polyoxyalkylene polymer (A), having a molecular weight of from 8000 to 50000 and having hydrolyzable silicon groups of the following formula (1), which comprises, as an essential component, the polyoxyalkylene polymer, having a molecular weight of from 80000 to 50000 and having hydrolyzable silicon groups of the formula (1), wherein a is 3 and a room temperature-setting composition containing a polyoxyalkylene polymer (A) having a molecular weight of from 8000 to 50000 and having hydrolyzable silicon groups of the formula (1), which comprises, as essential components, the polyoxyalkylene polymer having a molecular weight of from 8000 to 50000 and having hydrolyzable silicon groups of the formula (1) wherein a is 3, and a polymer (B) made by polymerization of a polymerizable unsaturated group-containing monomer (C): -SiX a R 1 3-a wherein R 1 is a C 1-20 substituted or unsubstituted monovalent organic group, X is a hydroxyl group or a hydrolyzable group, a is 1, 2 or 3, provided that when more than one R 1 exist, the plurality of R 1 may be the same or different, and when more than one X exist, the plurality of X may be the same or different.
