- 3. The fabric substrate of claim 2 wherein said vinyl-containing polysiloxane is a vinyl-containing polyalkylsiloxane and said ethylene-containing copolymer is ethylene-methyl acrylate.
- 4. The fabric substrate of claim 3 wherein said vinyl-containing polyalkylsiloxane is vinyl-containing polydimethylsiloxane.
- 5. The fabric substrate of claim 2 wherein said polysiloxane is a vinyl-containing polyalkylsiloxane and said ethylene-containing copolymer is ethylene-vinyl acetate.
- 6. The fabric substrate of claim 5 wherein said polyalkylsiloxane is vinyl-containing polydimethylsiloxane.
- 7. The fabric substrate of claim 2 wherein said coating composition comprises from about 50-95 parts by volume of the polysiloxane polymer and 5-50 parts by volume of the ethylene-containing copolymer.
- 8. The fabric substrate of claim 3 wherein said ethylene-methyl acrylate comprises from about 60-85 weight percent of ethylene and from about 15-40 weight percent of methyl acrylate.
- 9. The fabric substrate of claim 5 wherein said ethylene-vinyl acetate comprises from about 20-60 weight percent ethylene and from about 40-80 vinyl acetate.
- 10. An airbag fabric comprising the fabric substrate of claim 1.
- 11. An airbag fabric comprising the fabric substrate of claim 3.
- 12. An airbag fabric comprising the fabric substrate of claim 5.
- 13. A method of producing the fabric substrate of claim 2 comprising the steps of
(a) admixing said polysiloxane, said ethylene-containing copolymer, optionally an organic silane, optionally components selected from the group consisting of fillers, pigments, processing aids, and mixtures thereof, a solvent, and a curing agent; (b) applying the resultant admixture to the surface of a fabric substrate; (c) heating said fabric substrate to a temperature sufficient to evaporate said solvent from the fabric substrate surface; and (d) heating the resultant treated fabric substrate to a temperature sufficient to effectuate cross-linking of the polysiloxane and ethylene-containing copolymer on the fabric substrate surface.
- 14. The method of claim 13 wherein
said polysiloxane is polyalkylsiloxane; said ethylene-containing copolymer is ethylene-methyl acrylate; said curing agent is a peroxide; said solvent is an organic volatile solvent; said fabric substrate is an airbag fabric; said heating temperature of step “c” is from about 60 to about 90° C.; and said heating temperature of step “d” is from about 150 to about 200° C.
- 15. The method of claim 13 wherein
said polysiloxane is polyalkylsiloxane; said ethylene-containing copolymer is ethylene-vinyl acetate; said curing agent is a peroxide; said solvent is an organic volatile solvent; said fabric substrate is an airbag fabric; said heating temperature of step “c” is from about 60 to about 90° C.; and said heating temperature of step “d” is from about 150 to about 200° C.
- 16. An airbag fabric comprising the fabric substrate produced in accordance with the method of claim 13.
- 17. An airbag fabric comprising the fabric substrate produced in accordance with the method of claim 14.
- 18. An airbag fabric comprising the fabric substrate produced in accordance with the method of claim 15.
