MOISTURE CURABLE COMPOSITION

摘要

In conventional moisture curable compositions, it has been, difficult to control changes in the physical characteristics of the cured products to a low level when the cured products are left in a high temperature atmosphere of 80° C or more as a reliability test. The present invention is characterized by being able to control changes to a low level and having a slight change in elongation rate required to follow the expansion of an adherend under a high temperature atmosphere. The moisture curable composition contains components (A) to (D): component (A): an oligomer, in which a main skeleton is a (meth)acrylic polymer, having a hydrolyzable silyl group in the molecule component (B): a polydialkylsiloxane; component (C): a titanium catalyst; and component (D): a silane-based coupling agent having an isocyanurate skeleton.
