Abstract
An aqueous thermosetting protective coating composition cures by water evaporation followed by thermosetting crosslinking of the polymeric binder. The polymeric binder is ion-exchanged to remove cations and reduce the pH to less than 2.5 and comprises copolymerized ethylenic monomers including a beta-hydroxy ester monomer, whereby the polymer is self-curing by crosslinking by transesterification through hydroxy groups and beta-ester groups.
