    Abstract: Compounds comprising one or more functionalized fatty acid esters, which may be derived from bio-based oils, are used as a low-VOC coalescent agent (i.e., a coalescent agent having a low content of volatile organic compounds) in waterborne coating compositions. The functional group can be epoxide, vicinal diol, hydroxy phosphotriester, hydroxy ester, hydroxyl alkyl ester, hydroxyl benzyl ester, hydroxy ether, hydroxy amino, hydroxy sulfide, hydroxy nitrile, hydroxy amine, terminal alcohol, thiiran, ketone, or cyclic carbonate. The present disclosure also relates to waterborne coating compositions comprising these functionalized fatty acid esters.

    Abstract: The aqueous, substantially volatile organic compound (VOC)-free coating compositions of the invention include an acrylic latex and a vinyl acetate-ethylene latex including from about 10 to about 90 weight percent of a vinyl acetate-ethylene polymer, based on total weight of acrylic polymer and vinyl acetate-ethylene polymer, having a Tg from about −20 to about 20 degrees Celsius; and from about 10 to about 90 weight percent of an acrylic polymer, based on the total weight of acrylic polymer and vinyl acetate-ethylene polymer, the acrylic polymer comprising, in polymerized form, at least one ethylenically unsaturated (meth)acrylic monomer and from about 0.01 to about 10 weight percent, based on total weight of the acrylic polymer, of an acetoacetate moiety containing monomer, where the acrylic polymer has a Tg of from about −20 to about 20 degrees Celsius.
