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: A latex particle comprises an interior core and an outer shell. The core comprises an acrylic or vinyl polymer, and the shell comprises a water soluble alkyd polymer and at least one surfactant. Substantially all or all of the alkyd polymer is present in the shell of the latex particle and substantially none or none or the alkyd polymer is present in the core of the latex particle. Also described is a process for making the latex particle wherein the water soluble alkyd polymer is present as a co-surfactant during polymerization.

Abstract: A dispersion of an alkyd-containing polymer dispersed in water is used to form a waterborne coating composition; the alkyd-containing polymer being an acrylic-modified alkyd polymer, a silicone-acrylic-modified alkyd polymer, or a mixture thereof. The resulting waterborne coating composition includes about 2 to about 30% by weight of one or more thermal insulating fillers with the remainder being the alkyd-containing dispersion, such that the coating composition contains about 30 to about 80% by weight of the water and about 2 to about 50% by weight of the alkyd-containing polymer. The coating applied therefrom exhibits at least one of the following properties: a thermal conductivity that is less than 100 mW/mK; a weight retention of at least 70% after being heated up to 400 C as measured by thermogravimetric analysis (TGA) with a heating rate of 20 C/min.; or a weight loss of less than 50% up to a temperature of 470 C as measured by the TGA.
