More Information
Summary:The present invention provides aqueous compositions that provide improved open time, the compositions comprising (i) an aqueous polymer composition of one or more emulsion polymers, one or more aqueous dispersion polymers, or mixtures thereof, preferably, a vinyl or acrylic emulsion polymer, and (ii) from 0.1 to 5 wt.%, based on the total weight of solids in the composition, one or more polyalkoxylates having from 2 to 15 polyalkoxylate chains and an ethylene oxide (EO) content ranging from 20 to 70 wt.%, based on the total weight of polyalkoxylate solids in the composition. The compositions are useful in high solids or fast drying compositions such as coatings and non-cementitious mortars.
