Silicone rubber compositions for coating air bags, used for safety purposes to protect occupants of vehicles such as automobiles are described together with air bag fabrics coated with the composition and to air bags made from the coated fabric. The compositions are silicone rubber coating compositions which cure by hydrosilylation comprising an organopolysiloxane (A) having aliphatically unsaturated hydrocarbon or hydrocarbonoxy substituents, an organosilicon crosslinker having at least 3 silicon-bonded hydrogen atoms, a catalyst able to promote the reaction of the aliphatically unsaturated hydrocarbon or hydrocarbonoxy substituents with Si—H groups and a silica reinforcing filler, wherein the silica filler is pre-treated with 2% to 60% by weight based on the weight of the silica filler of an oligomeric organopolysiloxane containing Si-bonded methyl and vinyl groups and silanol end groups.
