Abstract
A scrim reinforced roofing membrane comprising a coated scrim layer having a first side and a second side and a first TPO layer on the first side of the coated scrim layer. 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. The warp yarns cross the weft yarns at crossing points. The scrim fabric has a polyvinyl acetate coating which is located along the length of the warp yarns and the weft yarns and between the warp and weft yarns at the crossing points. The coated scrim is at least partially embedded in the first TPO layer.
