1. An airbag comprising a coated fabric comprising:
(1) a woven or nonwoven substrate comprising polyester or polyamide;
(2) a coating derived from a coating composition which comprises (1) a dispersion comprising a melt blended product of:
(a) from 50 to 95 wt %, based on the total solids weight of the dispersion, of one or more olefinic base polymers;
(b) from 2 to 40 wt %, based on the total solids weight of the dispersion, of one or more dispersants;
(c) from 0 to 15 wt %, based on the total solids weight of the dispersion, of one or more compatibilizers;
(d) water; and
(e) optionally, base to neutralize the one or more dispersants from 100 to 140% of an acid value of the one or more dispersants; wherein the dispersion exhibits an average volume mean particle size diameter of less than or equal to 2 microns, a solids content of equal to or less than 70 wt %, and a pH of 8 or greater; (2) one or more rheology modifiers; and (3) optionally, one or more neutralizing agents such that the coating composition has a pH of greater than 7; wherein the coating is applied to at least one surface of the substrate at a total coating weight of from 20 to 50 g/m2; and
wherein the coated fabric exhibits a pressure retention of greater than or equal to 95% of an applied pressure of 200 kPa for a period of equal to or greater than 15 seconds.
