Abstract
Fabrics coated with an organopolysiloxane composition containing (a) an organopolysiloxane having aliphatic unsaturation, (b) an organohydrogenpolysiloxane having SiH groups in which the silicon to hydrogen ratio is from 10:1 to 1:1, (c) a catalyst which is capable of promoting the addition of SiH groups to the aliphatically unsaturated groups, (d) a hydrophobic silica filler, (e) a flame retardant and optionally an adhesion promoting agent. The coated fabric can be used in manufacturing air bags for automobiles.
Claims28
A fabric impregnated with a silicone composition comprising (a) an organopolysiloxane having aliphatic unsaturation, (b) an organohydrogenpolysiloxane having Si-bonded hydrogen atoms in a silicon to hydrogen ratio of from 10:1 to 1:1, (c) a catalyst capable of promoting the addition of SiH groups to the aliphatic unsaturated groups, (d) a hydrophobic silica filler, (e) a flame retardant and optionally (f) an adhesion promoting agent.
A process for coating a fabric with a silicone composition which comprises applying to the fabric a silicone composition comprising (a) an organopolysiloxane having aliphatic unsaturation, (b) an organohydrogenpolysiloxane having Si-bonded hydrogen atoms in a ratio of silicon to hydrogen of from 1:1 to 1:3, (c) a catalyst capable of promoting the addition of SiH groups to the aliphatic unsaturated groups, (d) a hydrophobic silica filler and (e) a flame retardant and optionally (f) an adhesion promoting agent.
