Patent ID: 7543843

Claim:
An airbag fabric comprising a fabric substrate and a polymer coating applied to at least one side of said fabric substrate, wherein said polymer coating comprises an interpenetrating network (IPN) of at least two resin components, the IPN being comprised of: (i) a first component, said first component being a urethane comprising at least one polyol segment selected from the group consisting of polytetramethyleneglycol, polycarbonate, silicon-based diol, and olefin-based diol; and (ii) a second component, said second component being selected from the group consisting of polyacrylates, polymethacrylates, vinyl polymers, and combinations thereof; wherein said polymer coating is characterized by a tensile strength of at least 1000 p.s.i. and wherein at least one component is characterized by a glass transition temperature of about 20° C. or less.
