Title: Polish compositions
IPC: C09G1/10
Filed: 1963-11-07
Abstract: A coating or impregnating composition, having a total solids content of at least 8% by weight, comprises an aqueous medium having dispersed therein a water-insoluble addition polymer and a wax, the proportions of polymer and wax being 10 to 95 parts by weight of polymer to 90 to 5 parts by weight of wax; said aqueous dispersion also containing a dispersing agent; 0 to 50% by weight (based on the weight of polymer) of an alkali soluble resin; and, dissolved in said aqueous medium, a polyvalent metal compound dissociable to form polyvalent metal ions other than, or in addition to, ions of calcium or magnesium. Long lists of suitable monomers are given. Copolymers exemplified are: ethyl acrylate/methyl methacrylate / methacrylic acid; ethyl acrylate / styrene / methacrylic acid; and ethyl acrylate / methyl methacrylate / dimethylaminoethyl methacrylate.  The above copolymers, in the form of emulsions produced by conventional emulsion polymerization, are blended with a wax emulsion comprising polyethylene wax, oleic acid and morpholine, together with an ammonia-soluble alkyd resin, plasticizers and surface-active agents to form floor polishes, and to each is added one of the following compounds: cadmium sulphate, aluminium diacetate, zinc acetate, barium acetate, nickel chloride, manganese sulphate, and zinc tetra-ammine benzoate.  The polishes are applied to vinyl and rubber floor tiles.  Many other surfaces, to which the compositions may be applied are specified. Conventional dyes, pigments and fillers may be incorporated in the compositions.ALSO:A coating or impregnating composition, having a total solids content of at least 8% by weight, comprises an aqueous emulsion containing a water-insoluble addition polymer and a wax, the proportions of polymer and wax being 10 to 95 parts by weight of polymer to 90 to 5 parts by weight of wax; said aqueous dispersion also containing a dispersing agent; 0 to 50% by weight (based on the weight of polymer) of an alkali soluble resin; and, disolve in said aqueous medium, a polyvalent metal compound dissociable to form polyvalent metal ions other than, or in addition to, ions of calcium or magnesium.
