Products / KEMPEROL AC Speed FR

KEMPEROL AC Speed FR is a quick-curing, cold liquid-applied polymethyl methacrylate (PMMA) roofing and waterproofing resin, fully reinforced with needle-punched polyester fleece, for exposed or buried applications that the maker says can allow same-day installation, including direct-to-deck, insulated and recover roof assemblies. Its technical data sheet reports a 90 mil membrane thickness with 120 fleece, an initial SRI of 108 for white and 27 for gray, a CRRC listing for the white only, and states the membrane achieves a Class A fire rating as part of an assembly in accordance with ASTM E 108 / UL 790. The product page and the data sheet print different figures for some properties, including tearing resistance (80 lbf on the page, 65 lbf on the data sheet) and dimensional stability (0.05 percent against 0.15 percent).
