Abstract
A curable organopolysiloxane composition is provided. The curable organopolysiloxane composition comprises: (A) an organopolysiloxane having at least two alkenyl groups per molecule; (B) an organosiloxane having one silicon atom-bonded hydrogen atom per molecule and free of alkenyl groups and silicon atom-bonded alkoxy groups; (C) an organosiloxane having one silicon atom-bonded hydrogen atom and at least one silicon atom-bonded alkoxy group per molecule and free of alkenyl groups; (D) an organopolysiloxane having at least two silicon atom-bonded hydrogen atoms per molecule and free of alkenyl groups and silicon atom-bonded alkoxy groups; (E) a hydrosilylation reaction catalyst; and (F) a condensation reaction catalyst. The curable organopolysiloxane composition can be cured to form a cured product. The cured product generally exhibits an excellent adhesion property against various substrates without cracking and delamination occurring after a thermal shock test.
