Aqueous stain-blocking coating composition

An aqueous stain-blocking coating composition including an aqueous emulsion copolymer having a glass transition temperature (Tg) from -20° C. to 60° C. and including, as polymerized units, at least one ethylenically unsaturated nonionic monomer and 1.5-6%, by weight based on the dry weight of the co...

More Information
Summary:An aqueous stain-blocking coating composition including an aqueous emulsion copolymer having a glass transition temperature (Tg) from -20° C. to 60° C. and including, as polymerized units, at least one ethylenically unsaturated nonionic monomer and 1.5-6%, by weight based on the dry weight of the copolymer, ethylenically unsaturated strong acid monomer, such as a Phosphorous-containing strong acid monomer, or salts thereof is provided. Also provided is a method for blocking stains by applying the aqueous stain-blocking coating composition to a substrate bearing a stain; and drying, or allowing to dry, the aqueous composition.
