Publication number: 20230250271Abstract: 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.Type: ApplicationFiled: April 13, 2023Publication date: August 10, 2023Inventors: Randall J.

Publication number: 20100216949Abstract: A method of making an alkoxylated polyethyleneimine (APEI) product having reduced discoloration includes treating a composition including a component selected from the group of polyethyleneimine (PEI), alkoxylated polyethyleneimine (APEI) intermediate, and combinations thereof that is used to make the APEI product. The method of treating the composition includes adding water to the composition in an amount of from 2 to 20 parts by weight, based on the total weight of the composition. The water is stripped from the composition within a relatively low temperature range of from 158 to 203° F. until less than or equal to 0.2 parts by weight of water, based on the total weight of the composition, is present in the composition. The aqueous solutions of APEI product thus made have Gardner color values of less than 6.Type: ApplicationFiled: February 7, 2006Publication date: August 26, 2010Applicant: BASF AKTIENGESELLSCHAFTInventors: Klaus J.
