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.

A latex emulsion that includes an aqueous carrier liquid and a latex copolymer formed from reactants comprising butyl methacrylate, wherein the reactants comprise at least 20 wt. % a vinyl monomer, based on the total weight of ethylenically unsaturated monomers in the latex copolymer. A homopolymer formed from the vinyl monomer preferably exhibits a glass transition temperature of between about &#x2212;10&#xb0; C. and about 30&#xb0; C. A coating formed from the latex emulsion preferably exhibits a dry adhesion of greater than about 4 pounds per linear inch when applied between a thermoplastic polyolefin roofing membrane and a plywood roofing substrate at an average coat weight of about 6 lbs/100 ftand subjected to 180&#xb0; peel testing according to ASTM D903 with a 2-inch per minute pull rate. The latex emulsion may include a second latex copolymer or stage, and may be used as part of an aqueous adhesive composition.
