  • Tape joint compound
    Patent number: 9683094
    Abstract: An aqueous tape joint compound including: an inorganic filler; an emulsion polymer binder; cellulose ether thickener; water; and from 0.01 to 1.3% by weight based on the weight of the aqueous joint compound, water-soluble polymer or salts thereof, the water-soluble polymer selected from the group consisting of (a) polymer consisting essentially of, as polymerized units, from 50% to 100%, by weight based on the weight of the polymer, acrylic acid, and from 0% to 50%, by weight based on the weight of the polymer, second monoethylenically unsaturated acid monomer, (b) diisobutylene-maleic anhydride polymer, and (c) mixtures thereof; the water-soluble polymer having a weight average molecular weight of from 1500 to 75,000 and a calculated Tg of from 80° C. to 250° C.; the aqueous tape joint compound being substantially free from calcium sulfate hemihydrate is provided.

  • Aqueous dispersion comprising a (meth)acrylic polymer and a vinyl acetate polymer
    Patent number: 8580873
    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.

  • Crack inhibitor for tape joint compositions
    Patent number: 5334243
    Abstract: The use of calcium oxide or calcium hydroxide as a crack-inhibiting additive for tape joint compositions is disclosed. Tape joint compositions containing calcium oxide or calcium hydroxide maintain their workability while experiencing less cracking upon drying.
