  • Voided latex particles containing functionalized outer shells
    Patent number: 11802173
    Abstract: The wet adhesion of a coating composition may be improved through the use of voided latex particles as opacifying agents which contain a hollow interior as well as an outer shell of a polymer containing functional groups such as amino, 1,3-diketo, urea or ureido. Other types of functional groups may be introduced to the outer shell polymer in order to vary other desired characteristics of the coating. The voided latex particles are non-film-forming.
    Type: Grant
    Filed: October 11, 2021
    Date of Patent: October 31, 2023
    Assignee: Arkema Inc.
    Inventors: Keith R. Olesen, Matthew F. Boudreaux, Lily Liu
