Silicone rubber coated fiberglass fabric with an organopolysiloxane composition containing :
(1) an organopolysiloxane having aliphatic unsaturation,
(2) an organohydrogenpolysiloxane having SiH groups in which the silicon to hydrogen ratio is from 10:1 to 1:1,
(3) a catalyst which is capable of promoting the addition of SiH groups to the aliphatically unsaturated groups,
(4) a hydrophobic silica filler,
(5) a flame retardant and optionally an adhesion promoting agent.
The coated fabric can be used in manufacturing air bags for automobiles.
