  • Ethylene/vinyl acetate latex binders and paints which are free of volatile coalescents and freeze-thaw additives
    Patent number: 6087437
    Abstract: The invention is directed to aqueous coating compositions which are freeze-thaw stable in the absence of conventional volatile coalescing solvents and volatile freeze-thaw (F/T) additives and which utilize a latex binder which contains an EVA thermoplastic interpolymer which is prepared by emulsion polymerization of ethylene, vinyl acetate and a monomer represented by structure (I) ##STR1## where R is hydrogen or a methyl group, X is O or NH, and n is an integer from 1 to 11 and to the latex binder which contains the EVA interpolymer.
    Type: Grant

  • Latex binders and coatings containing polymers derived from polymerizable saccharide monomers
    Patent number: 5719244
    Abstract: Latex binders are disclosed which are used to prepare freeze-thaw-stable latex coating compositions which may be free of volatile freeze-thaw/open-time additives. The latex binders are prepared by combining a polymer which is the polymerization product of a polymerizable saccharide monomer, an acrylic monomer and, optionally, a monomer selected from styrenic monomers, ionic monomer and wet adhesion monomers. The latex coating compositions are freeze-thaw stable, even in the total absence of a volatile freeze-thaw additive, and exhibit improved open-time when compared to a latex coating composition which does not contain a volatile freeze-thaw additive. Methods for preparing the freeze-thaw-stable latex coating compositions are also disclosed.
