COATING COMPOSITIONS FOR POLYMERIC ROOFING MATERIALS

A latex emulsion may include an aqueous carrier liquid and a latex copolymer formed from reactants comprising butyl methacrylate, wherein the reactants include at least 20 wt. % butyl methacrylate, based on the total weight of ethylenically unsaturated monomers used to make the latex copolymer. A co...

Beschreibung
Zusammenfassung:	A latex emulsion may include an aqueous carrier liquid and a latex copolymer formed from reactants comprising butyl methacrylate, wherein the reactants include at least 20 wt. % butyl methacrylate, based on the total weight of ethylenically unsaturated monomers used to make the latex copolymer. A coating formed from the latex emulsion exhibits a wet adhesion to a thermoplastic polyolefin roofing membrane of greater than about 1 pound per linear inch when tested using fabric embedded peel adhesion testing per ASTM C794. The latex emulsion may be used as part of an aqueous coating composition or a roofing system including a polymeric roofing membrane.
