Patent number: 11649346Abstract: Disclosed herein are aqueous coating compositions containing an anionically stabilized polymer, one or more derivatized polyamines, and a volatile base. Coating compositions can farther 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: GrantFiled: September 19, 2019Date of Patent: May 16, 2023Inventors: Randall Petrie, Luke S. Egan, Sridhar G. Iyer, Armin Burghart, Jeremy Funk

Patent number: 11021629Abstract: Two-part aqueous coating compositions as well as methods of using thereof are described. The first coating component can comprise one or more polymers and the second coating component can comprise a flocculant. The first coating component and the second coating component can be provided as separate aqueous compositions. The first coating component and a second coating component that can be co-applied (e.g., simultaneously or sequentially) to a surface form a rapid set coating.Type: GrantFiled: June 26, 2020Date of Patent: June 1, 2021Assignee: BASF CorporationInventors: Sridhar G. Iyer, Randall Petrie, Michael A. Guibault

Patent number: 10053597Abstract: Coating compositions and methods for their preparation are described. The coating compositions can include a first copolymer produced by emulsion polymerization and derived from one or more monomers including one or more (meth)acrylates, one or more acid monomers, and optionally styrene. The first copolymer can have a Tg from ?50° C. to ?23° C. and is present in an amount of 10-50% by weight based on the total polymer content. The coating compositions can also include a second copolymer produced by emulsion polymerization and derived from one or more monomers including one or more (meth)acrylates, one or more acid monomers, and optionally styrene. The second copolymer can have a Tg from ?15° C. to 25° C. and is present in an amount of 50-90% by weight based on the total polymer content. Further described herein are dried coatings, methods for coating a substrate, and methods for producing a coating.Type: GrantFiled: January 8, 2014Date of Patent: August 21, 2018Assignee: BASF SEInventors: Luke S. Egan, Robert Michael Calhoun, Armin Burghart, Randall Petrie, Randall Brennan
