  • Use of an organic sol of cerium in paints, particularly lacquers and varnishes
    Patent number: 7955431
    Abstract: The invention relates to the use of an organic cerium sol in paints, in particular finishes or varnishes, to improve durability. More particularly, the sol used can be a sol comprising an amphiphilic acid system, an organic phase and particles in the form of agglomerates of crystallites with a d80, advantageously d90, of at most 5 nanometers, 90% (by weight) of agglomerates comprising 1 to 5, preferably 1 to 3 crystallites. The paints incorporating a cerium sol have improved water resistance properties and mechanical properties.
    Type: Grant
    Filed: February 26, 2003
    Date of Patent: June 7, 2011
    Assignee: Rhodia Operations
    Inventors: Jean-Noel Bousseau, Bruno Echalier, David Fauchadour
  • Aqueous paint composition, particularly a lacquer or a varnish and an aqueous colloidal dispersion of cerium
    Patent number: 7462665
    Abstract: The invention relates to an aqueous paint composition, particularly a lacquer or a varnish and an aqueous colloidal dispersion of cerium. Said dispersion has a pH of at least 7 and comprises an organic acid with at least three acid functions of which the third pK is at most 10 or a salt of said acid with ammonia or an amine. Said composition has an improved water content and mechanical properties which improve throughout the life thereof or the duration of the presence thereof on the substrate for protection.
