However, when the modulus of the cured product or the cured product of the composition containing the compound is lowered, the stickiness of the surface of the compound, that is, tack, remains even after the curing is completed. When it is used as a base polymer for materials, it causes joint pollution such as adhesion of dust, which is a cause of impairing the appearance of buildings. For the purpose of preventing this tack, for example, JP-A-1
JP-A-146959 discloses a technique of adding an air-curable compound to a polymer having a hydrolyzable silicon-containing group. However, the air-curable compound does not exhibit its effect until time passes, and for example, tackiness immediately after the application of the sealant cannot be improved.

Further, in JP-A-64-9268, a rubber-like organic polymer having a reactive silicone group which can be cross-linked by forming a siloxane bond in the molecule has a specific structure and is hydrolyzed. Compositions are disclosed that comprise compounds that generate monomonosilanols. This method is effective for improving the initial tack, but since the curing speeds on the surface and inside are significantly different, it causes curing failure and surface peeling phenomenon, which limits the pot life. It was a constraint.
