REACTIVE PLASTICIZER AND CURABLE COMPOSITION CONTAINING SAME

摘要

To prevent such a problem that a liquid component bleeding out from a cured sealing material or adhesive contaminates a coating film that is coated over the cured sealing material or adhesive or members around the cured sealing material or adhesive. To provide a curable composition having high elastic recoverability, which is suitable for working joints. A reactive plasticizer which is composed of an organic polymer having an average molecular weight of 800-15,000 and containing an average of 0.5 or more but less than 1.2 specific reactive silicon groups per molecule is used.
