Abstract:
1. A water redispersible polymer powder composition comprising an admixture of powders, wherein the admixture of powders comprises: a) a first powder which is a water redispersible polymer powder (RDP), said water redispersible polymer powder (RDP) comprising a co-dried admixture of a water insoluble film-forming polymer and a colloidal stabilizer, said film forming polymer comprising a carboxylated styrene-butadiene copolymer or the copolymerization product of styrene, butadiene, a carboxylic acid and one or more other monomer and b) a second powder comprising a polyglycol which is a polyethylene glycol, a polypropylene glycol, or any other polyether diol or triol, the amount of the polyglycol being from 0.001% by weight to 10% by weight, based upon the weight of the water redispersible polymer powder (RDP).
