Abstract: 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.

Abstract: Regarding a durability test of a moisture-curing composition, it is difficult to both suppress foaming in the inside of a cured product and to stably maintain the physical properties of a cured product. A moisture-curing composition containing the components (A) to (D), the moisture-curing composition containing 0.5 to 5.0 parts by mass of the component (C) relative to 100 parts by mass of the component (A): Component (A): an oligomer which has a polymer of (meth)acrylic monomers as a main chain and which has a hydrolyzable silyl group in the molecule Component (B): specific polydialkylsiloxane Component (C): silicate Component (D): a curing catalyst.
