  • Patent number: 11098176
    Abstract: The present invention is directed to formulations including a polymer and a plasticizer composition. The plasticizer composition is a blend of an alkyl ketal ester plasticizer and a second plasticizer selected from a cycloaliphatic compound, an ortho phthalate compound, a terephthalate compound, a benzoate ester compound, and a bio-based compound. The plasticizer composition is at least 10% by weight of the total of the polymer and the plasticizer composition.
    Type: Grant

  • Patent number: 8362142
    Abstract: The present invention discloses polyurethane dispersions based on aliphatic isocyanates which form hard coatings wherein the coatings also have good solvent resistant properties. The enhanced properties of the coatings are achieved by including from 1 to 8 weight percent of a high functional polyol in the polyol formulation for producing the dispersions.

  • Publication number: 20050061203
    Abstract: Coating compositions comprising a pigment and starch dispersion of discrete crosslinked starch particles in an aqueous liquid. The dispersion may be used as coating color for paper. A preferred process of preparing the dispersion of starch particles comprises (a) obtaining a mixture of starch and an aqueous liquid; (b) processing the mixture using shear forces in the presence of a crosslinker in an extruder; and (c) injecting a hydroxylic liquid into the extruder and dispersing the mixture inside the extruder or outside the extruder or both inside and outside the extruder to obtain the dispersion.

  • Patent number: 6753355
    Abstract: This invention concerns a composition useful for preparing latex foam. The composition includes a latex and a polynitrile oxide such as 2,4,6-triethylbenzene-1,3-dintrile oxide, or a latex and an epoxy silane, or a latex and a mixture of the two crosslinkers. The composition may also contain additional components, including fillers, surfactants, cell detackifiers, froth stabilizers, froth boosters, viscosity reducers, compounds to improve resilience and antioxidants. The composition is particularly useful in the manufacture of flooring, wall covering, shoe lining and non-woven materials.
