Abstract
An addition-type silicone rubber composition comprising (a) an organopolysiloxane containing at least two alkenyl groups bonded to the silicon atoms in one molecule, (b) an organopolysiloxane containing one alkenyl group bonded to the silicon atom in one molecule on an average, (c) an organohydrogenpolysiloxane containing at least two hydrogen atoms bonded to the silicon atoms, (d) a platinum catalyst; and a product of curing the composition. This silicone rubber composition can give a low-modulus silicone rubber by curing which neither contaminates the material in contact therewith nor deforms owing to shrinkage, without hindering the adhesion of the composition during its curing stage.
