Abstract:
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 linear trimethyl terminated polydimethyl methylhydrogen siloxane containing at least two silicon-bonded hydrogen groups per molecule; Ld) a hydrosilylation cure catalyst; (e) an organosilicon resin; 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. Air bags and air bag fabrics can be coated with the hydrosilylation curable textile coating composition, and the resulting air bags and fabrics generally have enhanced scrub resistance.
