Abstract
A waterborne coating composition includes an aqueous polyurethane resin, a reactive silicone component, and a crosslinker. The aqueous polyurethane resin can have urethane linkages, hydrazinecarboxamide linkages, and reactive hydrazide functional groups. The polyurethane resin can have a glass transition temperature of less than 25° C. Methods of preparing waterborne coating compositions and substrates at least partially coated with waterborne coating compositions are also disclosed.
