Abstract:
1. A binder composition consisting essentially of: a. at least one polycarboxy emulsion copolymer comprising as copolymerized units from 12% to 20% by weight of a carboxy acid monomer, wherein said copolymer has a measured glass transition temperature (Tg) of from 40° C. to 70° C., and a total weight solids of no less than 40%; and b. at least one polyol crosslinker having a molecular weight of less than 700, wherein said polyol crosslinker comprises a primary hydroxy group and at least one additional hydroxy group, wherein the ratio of primary hydroxy group equivalents to carboxy group equivalents is from 0.25:1 to 2.0:1, and further wherein the composition does not include any polymers containing less than 10% by weight of a carboxy acid monomer.
