Abstract: The invention provides curable waterborne coating compositions comprising an aqueous dispersion (A) comprising an organic binder component (A1) comprising at least 5% by weight of a reactive component (a), based on the total weight of organic binder component (A1), and at least one crosslinking component (B). The reactive component (a) is substantially free of any heteratoms and is a not a crystalline solid at room temperature and comprises from (i) 12 to 72 carbon atoms, and (ii) at least two functional groups. The curable waterborne coating compositions of the invention show significantly improved pop resistance while also providing improved chip resistance, weathering resistance, flexibility, and/or scratch & mar resistance.

Abstract: A method for providing cured coating films free of popping defects. The method requires the application to a substrate of at least 2.0 mils/50.8 microns of a uncured curable coating composition comprising an anti-popping component (a), a film-forming component (b), and a crosslinking component (c), wherein anti-popping component (a) has from 12 to 72 carbon atoms, is substantially free of any heteroatoms, is not a crystalline solid at room temperature and comprises a mixture of two or more structures selected from the group consisting of aliphatic structures for anti-popping component (a), aromatic-containing structures for anti-popping component (a), cycloaliphatic-containing structures for anti-popping component (a), and mixtures thereof, at least one of the two or more structures being a cycloaliphatic-containing structure or an aromatic-containing structure. The coated uncured substrate is cured to provide a cured film free of popping defects with an average film build of at least 2.0 mils/50.8 microns.
