Duro-Last EV incorporates DuPont Elvaloy KEE (ketone ethylene ester) into Duro-Last's thermoplastic membrane formulation for added chemical resistance and cold-weather flexibility, reinforced with an 18x9 weft-inserted, anti-wicking polyester scrim. It meets ASTM D4434 Type III requirements and is offered in 50, 60, and 80 mil thicknesses in white. It can be mechanically fastened, induction-welded, or adhered, though it must not be adhered with Duro-Last Solvent-Grip spray adhesive.
