An organopolysiloxane composition which has improved adhesion and is curable at an elevated temperature in the presence of atmospheric moisture comprising: (a) An organopolysiloxane having an average of at least two hydroxyl groups per molecule; (b) an organosilicon compound containing at least two hydrolyzable groups per molecule which is capable of reacting with the hydroxyl groups of the organopolysiloxane; (c) an organohydrogenpolysiloxane containing at least one silicon-bonded hydrogen atom per molecule; (d) a platinum catalyst; and (e) if desired, a condensation catalyst. The resultant composition is generally heated to an elevated temperature to form an elastomer.
