A hydrosilylation curable textile coating composition comprises: (a) a linear organopolysiloxane polymer having at least two alkenyl and/or alkynyl groups per molecule; (b) a reinforcing filler comprising at least one of fumed silica, precipitated silica, or calcium carbonate; (c) a cross-linker containing at least two silicon-bonded hydrogen groups per molecule; (d) a hydrosilylation cure catalyst; (e) an organosilicon resin containing M and Q units; and (f) an adhesion promoter comprising a mixture and/or reaction product of (i) one or more alkoxysilanes having an epoxy group in the molecule; (ii) a linear organopolysiloxane oligomer containing at least one alkenyl group and at least one hydroxy or alkoxy group per molecule; and (iii) an organometallic condensation reaction catalyst comprising organoaluminum or organozirconium compounds. A textile, e.g. air bag or air bag fabric, can be coated with the hydrosilylation curable textile coating composition, and resulting air bags and fabrics generally have improved properties.
