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. Fabric treated with this material in the manner described herein permits reduction in the cost of the coating itself (by reducing the use of expensive silicone polymers). Airbag fabrics and cushions, as well as methods of making and using such a novel airbag coating material are also encompassed within this invention.
