Abstract

A liquid curable silicone adhesive composition is provided. The composition is generally storage stable as a one-part composition at room temperature, can primarily cure at room temperature in the presence of moisture, and can secondarily cure at high temperatures, and can form a strong adhesive layer on a substrate or member. The liquid curable silicone adhesive composition comprises: a curable reactive organopolysiloxane which has a radical reactive group and a condensation reactive group in the same molecule or throughout the mixture; a condensation reaction catalyst; an organic peroxide; an adhesion imparting agent; and a crosslinkable silane. Herein, regarding the storage modulus (G') of a cured product obtained by primarily curing the composition in the presence of moisture approximately at room temperature, along with the storage elastic modulus (G′) of a cured pro duct obtained by curing the composition, the increase rate (Δ) of the storage elastic modulus is at least 50%.
