WATERBORNE COATING COMPOSITIONS CONTAINING LOW-VOC COALESCENTS

摘要

Waterborne coating compositions are disclosed that include a latex emulsion polymer, and, as a coalescent, a levulinic acid ester of a monohydric aliphatic alcohol having from 10 to 20 carbon atoms. The coating compositions of the invention have a reduced VOC content, and provide improved coalescing activity compared with esters of polyols such as glycerol.
