ABSTRACT:
The present disclosure is directed to the use of specific hybrid resins as airbag coatings. Preferably, the polymers used to create these hybrid resins, as described herein, are urethanes blended with acrylates, vinyls, silicones, and combinations thereof, where at least one of the components has a glass transition temperature of 20° C. or less. The urethanes are preferably of the polycarbonate, polytetramethyleneglycol, silicon-based diol, or olefin-based diol type. The hybrid resins may be produced in an aqueous dispersion, in a solvent, or by mixing the polymers together where one polymer is dissolved directly into a second polymer to form a continuous matrix. The resulting hybrid resins exhibit a tensile strength of at least 1,000 p.s.i. and an elongation at break of at least about 200%.
