  • Patent number: 11180649
    Abstract: An aqueous dispersion comprising: (a) a latex binder, wherein the latex binder comprises: (i) about 1-25% by weight of a monomer having latent crosslinking functionality, (ii) 0.1 to about 15% of an acid functional monomer, (iii) about 1 to about 25% ethylenically functional silica, (iv) and about 35 to 97.9% other monomers; and (b) an aqueous unsaturated silane treated silica dispersion, wherein the unsaturated silane treated silica dispersion comprises colloidal ethylenically unsaturated silica particles having an average particle size less than about 100 nm.

  • Patent number: 9000069
    Abstract: The present invention relates to coating compositions formed by combining two latex resins: a base latex resin and a stratifying latex resin. The stratifying latex resin comprises at least one “driver” to promote migration of the stratifying latex to the surface of the coating during curing or drying. Drivers may be selected from one or more of fluorine containing monomers incorporated into the stratifying latex, long chain acrylate monomers, such as lauryl methacrylate, wax, small particle size, or relatively low Tg.
