Abstract:
An aqueous dispersion, liquid or spreadable at 20Â° C., and useful as a binder, sealing or coating composition, consisting essentially of water, a homopolymer or copolymer of styrene containing at least 30% by weight of styrene or methyl styrene, and a fatty compound, wherein a ratio by weight of the styrene polymer or styrene copolymer to the fatty compound is from 100:0.5 to 100:15 wherein said fatty compound comprises at least one member selected from the group consisting of fatty acids, fatty alcohols, and derivatives thereof, wherein the fatty acids and fatty alcohols contain an aliphatic group having more than 12 carbon atoms and, optionally a member selected from the group consisting of antioxidants, pigments, fillers, preservatives, defoamers, film forming agents, fragrances, adhesion promoters, solvents, dyes, flameproofing agents, flow controllers, resins, tackifiers, viscosity regulators, dispersion aids, emulsifiers and mixtures thereof, and wherein said aqueous dispersion has a solids content of 20% to 85% by weight and the dried aqueous dispersion is non-staining when stored between sheets of silicone paper for three weeks at 60Â° C.
