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.
