Liquid silicone rubber coating compositions which include specific amounts of an organopolysiloxane bearing at least two alkenyl groups, an organohydrogenpolysiloxane bearing at least two silicon-bonded hydrogen atoms, a crosslinking reaction catalyst which is an organic peroxide, a finely divided silica and a tackifier have a good coatability even when not diluted with a solvent. In airbags obtained by coating such a composition onto a woven base fabric and curing the applied composition, the cured coat does not delaminate during airbag inflation, thus minimizing inflator gas leakage and resulting in excellent inflation time sustainability.
