ABSTRACT:
A curable organopolysiloxane composition which cures freely, uninhibited by moisture or heat, and the cured silicone substance formed has excellent adhesive strength to various substrates when cured in contact with them. The curable organopolysiloxane composition 100 parts by weight of an organopolysiloxane mixture of an alkoxy-organopolysiloxane with a viscosity at 25.degree. C. of 0.02-1,000 Pa.s and at least two silicon-bonded alkoxy groups in each molecule and an alkenyl-organopoly-siloxane with a viscosity at 25.degree. C. of 0.02-1,000 Pa.s and at least two silicon-bonded lower alkenyl groups in each molecule; an organohydrogenpolysiloxane having at least two silicon-bonded hydrogen atoms in each molecule and in an amount such that there are 0.3-5 mols silicon-bonded hydrogen atom per one mol of the silicon-bonded lower alkenyl groups in the composition; 0.1-20 parts by weight of an alkoxysilane represented by the following formula or its partial hydrolysis condensate
