ABSTRACT:
The invention provides a method for the preparation of a cured silicone rubber body by curing at room temperature and yet free from the problems of the low shape-retainability before curing of the conventional room temperature-vulcanizable silicone rubber compositions and the relatively poor mechanical strengths of the cured bodies thereof due to the use of relatively low molecular weight components therein. The method comprises shaping an organopolysiloxane composition comprising an organopolysiloxane of a sufficiently high molecular weight having at least two aliphatically unsaturated hydrocarbon groups, e.g. vinyl groups, per molecule and a platinum catalyst into a desired form and contacting the shaped form with an organohydrogenpolysiloxane in a liquid form so that the latter siloxane diffuses through the shaped body and pertains to the crosslinking reaction with the unsaturated groups in the former siloxane as catalyzed by the platinum catalyst to give a cured silicone rubber body.
