Claims9
A method of coating a carpet, comprising coating the carpet with a mixture comprising an aqueous dispersion of a vinyl acetate polymer and an aqueous dispersion of a vinyl acetate-ethylene copolymer.
A carpet coating composition prepared from a mixture comprising an aqueous dispersion of a vinyl acetate polymer and an aqueous dispersion of a vinyl acetate-ethylene copolymer, and 100 to 1400 wt % of fillers, based on the weight of the mixture of vinyl acetate polymer and vinyl acetate-ethylene copolymer (dry/dry), and water, and optionally one or more additives and optionally one or more added substances, wherein the vinyl acetate-ethylene copolymer is obtained via free-radically initiated emulsion polymerization in an aqueous medium of 65 to 98 wt % of vinyl acetate and 2 to 30 wt % of ethylene and optionally up to 10 wt % of further comonomers, all based on the total weight of the monomers, and wherein the mixture of the aqueous dispersions and the filler has a Brookfield viscosity of <7000 mPas at a solids content of 75 to 85 wt % before the admixture of additives and added substances.
