Abstract
The present invention relates to an aqueous dispersion comprising (a) at least one (meth)acrylic polymer; (b) at least one vinyl acetate polymer selected from vinyl acetate homopolymer and vinyl acetate copolymers comprising in polymerized form vinyl acetate and ethylene; (c) water; and (d) optionally up to 50% by weight of an inorganic filler, based on the total weight of the aqueous dispersion, wherein the weight ratio of (meth)acrylic polymer(s) (a) to vinyl acetate polymer(s) (b) is from 70:30 to 30:70. The aqueous dispersion may be used as a joint compound or sealing compound.
