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 invention relates to a high shear stable aqueous fluoropolymer coating composition, preferably using polyvinylidene fluoride (PVDF), such as KYNAR® PVDF, suitable for high performance coating applications. The composition is based on a high shear stable fluoropolymer emulsion having small particle size, blended with an acrylic polymer additive. The use of this composition allows high bake PVDF water-base coatings which can be applied on variety of substrates such as metal or ceramic surfaces, and in the impregnation of textiles, glass, carbon or aramid fibers, etc. The dry coating formed from the coating composition of the invention exhibits improved gloss, crack resistance, chemical resistance, hot dirt pick up resistance and other improved properties.
