Abstract: Disclosed herein are aqueous coating compositions containing an anionically stabilized polymer, one or more derivatized polyamines, and a volatile base. Coating compositions can further include one or more additional copolymers, which may or may not be anionically stabilized, and/or additional additives, including pigments, defoamers, pigment dispersing agents, thickeners, surfactants, and combinations thereof. By incorporating a derivatized polyamine, such as an alkoxylated polyamine, the setting time of the coating compositions can be decreased. Also provided are coatings formed from the coating compositions described herein, as well as methods of forming these coatings.
