More Information
Summary:The present invention provides two-component compositions comprising a component A) one or more acrylic aqueous emulsion copolymer having a measured glass transition temperature (Tg) of from −20 to 0° C. and which is the copolymerization product of (i) from 60 to 89.9 wt. % of one or more nonionic (meth)acrylic monomers, (ii) from 10 to 40 wt. % of one or more vinyl aromatic monomers, (iii) from 0.1 to 2.0 wt. % of one or more monomers chosen from itaconic acid, methacrylic acid, amides of a,β-unsaturated C3 to C6 carboxylic acids, and mixtures thereof, all wt. %s of monomers based on the total monomer solids, wherein the aqueous emulsion copolymer has at least one residue of an ascorbic acid reducing agent or is the copolymerization product of a monomer (iii) comprising itaconic acid, and, a separate component B) comprising a fast curing dry mix powder composition of a hydraulic cement and a high alumina content cement.
