Abstract

See full text

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 −10° C. and about 30° 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 ft2 and subjected to 180° 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.
