(57) [Abstract] [Problem] To maintain fluidity under sealed and light-shielded conditions, but rapidly form a non-fluid adhesive substance by irradiation with high energy rays such as ultraviolet rays and electron beams, and then by moisture in the atmosphere. Provided are a curable organopolysiloxane composition which can be further elasticized by a curing reaction, and a method for adhering a substrate and an adherend using the composition. SOLUTION: (A) an alkenyl group-containing silicone resin, (B) a mercapto group-containing siloxy group-containing siloxy group-containing silicon atom-bonded alkoxy group (the organopolysiloxane does not contain an alkenyl group), and (C). A curable organopolysiloxane composition comprising a mercapto group-containing organosilane and (D) a condensation reaction accelerating catalyst and having a viscosity at 25 ° C. of not more than 30,000 poise, and after applying the composition to a substrate, A method of adhering a substrate to an adherend by irradiating with energy rays, then bringing the adherend into contact with the irradiation surface, and then leaving this in the atmosphere. |
