Room temperature-setting composition

摘要

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 formula (1), which comprises, as the polyoxyalkylene polymer (A), both the polyoxyalkylene polymer containing the hydrolyzable silicon groups of the formula (1) wherein a is 1 or 2, and the polyoxyalkylene polymer containing the hydrolyzable silicon groups of the formula (1) wherein a is 3 and 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 the polyoxyalkylene polymer (A), the polyoxyalkylene polymer containing the hydrolyzable silicon groups of the formula (1) wherein a is 1 or 2, and the hydrolyzable silicon groups of the formula (1) wherein a is 3 simultaneously.
