Abstract: Non-aqueous ionomeric coatings useful as protective surface coatings applied to a substrate are produced by combining a carboxyl functional polymer with zinc carbonate. Upon heat curing the applied film, the zinc cation clusters with the carboxyl polymer to produce a thermoset coating film.

Abstract: Heat cured, thermoset protective surface coating films applied to a substrate are produced preferably by a dual cure of a polymeric ionomeric binder comprising zinc modified carboxyl functional epoxy-ester polymers. The epoxy-ester polymer contains both carboxy and hydroxyl functionality and coreacts with a zinc salt selected from a zinc carbonate or an organic zinc salt having a pKa above about 3.0. Upon heat curing, the carboxyl and hydroxyl groups crosslink while the zinc forms a zinc cluster to produce a thermoset film.

Abstract: The pigmented paint coating composition is based on a cationic free polymeric binder comprising a cationic free, functional emulsion polymer and glycoluril where the emulsion polymer are adapted to coreact to form a thermoset paint film, and said polymeric binder is combined with a low-cation opacifying pigment. The process comprises copolymerizing ethylenically unsaturated monomers, including functional monomers but excluding amine monomers, in an aqueous polymerization medium, to produce the reactive emulsion polymer. The emulsion polymer and the glycoluril derivative are treated with ion-exchange step to produce the cation-free polymeric binder.
