A new adhesive coating composition, particularly for use on airbag fabrics which is composed of a silicone polymer and an appreciable level of a copolymer of ethylene and a polar monomer is provided. This coating provides , excellent adhesive properties to the coated fabric and provides a synergistic effect such that lower gas permeability upon inflation may be obtained with this coating than might be achieved with the silicone polymer alone. Additionally, such a coating allows maximization of the adhesion characteristics on one-piece woven airbag fabric such that blistering upon high-pressure inflation can be reduced while retaining a high degree of , inflation gas retention.

Why it's free to use
- Filed August 6, 2003. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 6, 2023.
