The coated scrim layer contains a scrim fabric which contains a plurality of warp yarns in a first direction and a plurality of weft yarns in a second direction approximately perpendicular to the first direction, where the warp yarns cross the weft yarns at crossing points. The coated scrim also contains a coating which contains polyvinyl acetate and second polymer where the second polymer is fluorocarbon-free. The coating contains less than about 0.01% wt. fluorine and is located along the length of the warp and weft yarns and is located between the warp and weft yarns at the crossing points.
