A binder composition for aqueous coatings that exhibit high gloss and superior corrosion resistance when applied to metal substrates comprising an aqueous emulsion copolymer, the copolymer including as polymerized units, at least one ethylenically unsaturated monomer and an ethylenically unsaturated strong acid monomer, such as phosphorus containing monomers, particularly phosphoethylmethacrylate; or salts thereof. Also provided is a method for achieving high gloss and superior corrosion resistance of metal substrates by coating a substrate with an aqueous coating composition comprising the binders of the present invention and drying, or allowing to dry, the aqueous composition.

The method of the present invention provides a coated cementitious substrate with a glossy appearance, dirt pick-up resistance, and efflorescence resistance. The method includes the steps of applying a coating formulation onto a green cementitious substrate and of curing the coated green cementitious substrate. The coating formulation contains an emulsion polymer with a molecular weight in the range of 30,000 to 300,000 and a glass transition temperature in the range of -10 C. to 60 C. Also provided are an emulsion polymer including a photoinitiator monomer as polymerized unit, a coating formulation including photoinitiator molecule, and a coating formulation including an ethylenically unsaturated polymer.
