Beschreibung
Zusammenfassung:	The present invention provides aqueous compositions which have low or zero volatile organic content (VOC) comprising (i) an open time additive composition of one or more phosphorus acid salts, preferably a phosphoric acid salt, and 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 (i) additive compositions may have a solids content as high as 95 wt.%. Further, the compositions may comprise (ii) one or more aqueous polymer, such as for use in coatings or non-cementitious mortars.
