  • Electrocoating binders which are water-dilutable on protonation with an acid, for the production of thick coating films, based on monofunctionally initiated epoxy resins
    Patent number: 5130350
    Abstract: Cathodic electrocoating binders which are water-dilutable on protonation with an acid are obtainable by reactingA) an epoxy compound or a mixture of epoxy compounds having an epoxide equivalent weight of less than 2,000 withB) a compound which is monofunctional with respect to epoxides and contains aliphatic or phenolic OH groups andC) a secondary amine of 2 to 36 carbon atoms, with the proviso that the reaction product of A), B) and C) still contains free epoxy groups, andD) an amount of an amidoamine containing primary amino groups which is equivalent to or greater than the amount of these free epoxy groups, the said amidoamine being obtainable from a primary diamine and a mono- and/or dicarboxylic acid.
    Type: Grant
    Filed: April 8, 1991
    Date of Patent: July 14, 1992
    Assignee: BASF Lacke & Farben Aktiengesellschaft
    Inventors: Thomas Schwerzel, Hans Schupp, Dirk Lawrenz, Hans Oslowski, Ulrich Heimann
  • Based on monofunctionally initiated, polyaminoamide modified epoxy resins
