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 ora roofing system including a polymeric roofing membrane. 胶乳乳液可包含含水载液和由包含甲基丙烯酸丁酯的反应物形成的胶乳共聚物，其中所述反应物包含基于用于制备所述胶乳共聚物的烯键式不饱和单体的总重量的至少20重量％的甲基丙烯酸丁酯。当根据ASTM C794使用织物嵌入剥离附着力测试进行测试时，由胶乳乳液形成的涂层表现出大于约1磅/线英寸的对热塑性聚烯烃屋顶膜的湿附着力。胶乳乳液可用作含水涂料组合物或包括聚合物屋顶膜的屋顶体系的一部分。
