  • Publication number: 20210309791
    Abstract: A two-component polyurethane composition comprising: an aqueous dispersion comprising an emulsion polymer and a specific sulphate and/or sulfonate surfactant, and a water-dispersible polyisocyanate; the emulsion polymer with a weight average molecular weight of 70,000 g/mol or less comprising, by weight based on the weight of the emulsion polymer, greater than 0.25% of structural units of a phosphorous-containing acid monomer and/or salts thereof, greater than 15% of structural units of a hydroxy-functional alkyl (meth)acrylate, structural units of an monoethylenically unsaturated nonionic monomer, and from zero to 10% of structural units of an additional acid monomer and/or salts thereof; and a process of preparing the two-component polyurethane composition.

  • Patent number: 11130878
    Abstract: This invention generally relates to a coating composition which provides a coating film with high hydrophilic resistance and high hydrophobic resistance. The coating composition contains a polymer formed from a monomer composition comprising (a) 45-85 wt % of ethyl ester of acrylic acid or methacrylic acid and (b) 15-54 wt % of itaconic ester with 1 or 2 carbon atoms as a binder of the coating composition, and the weight of sum of (a) and (b) is 65% or more based on the total weight of the polymer.
