The presence of an incompatible liquid, polydiorganosiloxane wherein from 1 to 30 percent of the siloxane units contain an ethylenically unsaturated hydrocarbon radical in high-consistency organosiloxane compositions that cure by a platinum-catalyzed hydrosilation reaction substantially improves the tear strength and elongation of cured elastomers prepared from these compositions.
