Abstract
The present application relates to a waterborne polymer system suitable for two-component polyurethane coating applications. Provided herein is a waterborne polymer system comprising: 1) a silicone-modified acrylic emulsion comprising: about 1% to about 30% by weight silicone based on resin solids; and at least one hydroxyl functional acrylic monomer; and 2) at least one secondary binder comprising at least one acrylic emulsion, at least one water-reducible polyester polyol, at least one polyurethane dispersion, or combinations thereof; wherein the silicone-modified acrylic emulsion has a Tg of about −50° C. to about 20° C.; and wherein a hydroxyl equivalent weight (OH EW) of the silicone-modified acrylic emulsion is about 400 g solid/mol or less. A waterborne coating is also disclosed comprising the waterborne polymer system described herein. These waterborne polymer system and two-component water-borne coating compositions including the silicone-modified acrylic emulsion are capable of achieving high chemical resistance, strong adhesion, especially after weathering, and excellent scratch and mar resistance at low gloss.
