An aqueous polymer composition comprises (A) a specific emulsion polymer comprising structural units of a cycloalkyl (meth)acrylate, structural units of an acetoacetoxy or acetoacetamide functional monomer, and structural units of a phosphorous acid monomer, a salt thereof, or mixtures thereof; and (B) a specific amount of a waterborne resin comprising at least one fatty acid ester segment and having a number average molecular weight of 20,000 g/mol or less, based on the total dry weight of the emulsion polymer and the waterborne resin. A coating composition comprising such aqueous polymer composition provides coatings made therefrom with improved anti-corrosion property.

Aqueous polymer composition and method of preparing thereof

A two-component polyurethane composition comprising (A) an aqueous dispersion comprising an emulsion polymer and from 2% to 20% of an alcohol alkoxylate of formula (I), by weight based on the weight of the emulsion polymer, and (B) a polyisocyanate; the two-component polyurethane composition can provide coatings with a high distinctness of image.

Two-component polyurethane composition

An aqueous dispersion comprising a multistage polymer comprising a first polymer and a second polymer that comprises structural units of an ethylenically unsaturated siloxane monomer, the multistage polymer comprising, by weight based on the weight of the multistage polymer, 4.5% or more of structural units of the ethylenically unsaturated siloxane monomer, and the coagulum content of the aqueous dispersion is less than 2,000 ppm after filtration through a 44 micron sieve.

Aqueous polymer dispersion and process of making the same

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.

An aqueous dispersion comprising a silicone-acrylic polymer with reduced coagulum, a process of preparing the aqueous dispersion, and an aqueous coating composition comprising the aqueous dispersion and providing coatings with improved corrosion resistance.

An aqueous dispersion and an aqueous coating composition comprising the aqueous dispersion, and the aqueous coating composition providing coatings made therefrom with improved anti-corrosion property and good water resistance and block resistance.
