Abstract: An anionically-stabilized aqueous emulsion composition includes a) a first emulsion polymer having a Tg from −60° C. to 40° C.; b) a volatile base; and c) polymeric particles, different from the first emulsion polymer and present in emulsified form. The c) polymeric particles are polyamine graft copolymers, in which vinyl monomers form a polymer grafted to a water-soluble amino-group containing polymer. The anionically-stabilized aqueous emulsion composition may have a pH of from 8 to 11.

Abstract: A method of coating a cementitious and/or masonry substrate includes applying an aqueous coating composition to the cementitious and/or masonry substrate. The aqueous coating composition includes at least one pigment, optionally at least one filler, at least one emulsified polymeric binder, at least one water-soluble silicate, and optionally at least one additive. The emulsified polymeric binder includes at least one of: a)(meth)acrylamide or derivative thereof as a polymerized monomer; or b) 1 weight % or more of at least one surfactant based on the total dry weight of the total monomer in the emulsified polymeric binder. The aqueous coating composition has a weight ratio of emulsified polymeric binder to the water-soluble silicate from 65:35 to 95:5 on a dry weight basis. The aqueous coating composition also has a pigment volume concentration (PVC) from 5% to 85.

Abstract: Waterborne dispersions including crosslinkable multistage polymeric particles useful in coating compositions are provided. The multistage particles have a last-formed layer that includes a diketone functionality that is capable of crosslinking via a dihydrazide component also included in the dispersion. Another embodiment of the waterborne dispersion further includes crosslinkable latex particles having a diketone functionality that are capable of crosslinking with each other and/or the multistage particles via the dihydrazide component. An emulsion polymerization process for forming the multistage particles also is provided. Also provided are coating compositions that contain either embodiment of the waterborne dispersions.
