  • Patent number: 4981887
    Abstract: To improve chip resistance of an alkyd-type electro-depositable coating composition, there may be added to the composition an ethylenically unsaturated, addition-polymerizable monomer or oligomer having a substantially linear backbone, having a molecular weight of at least about 150, and being reactive with fatty acid unsaturation of the alkyd.
    Type: Grant
    Filed: December 28, 1989
    Date of Patent: January 1, 1991
    Assignee: The Valspar Corporation
    Inventors: Philip J. Ruhoff, Rodney W. Stockstad, James A. Prevost, Larry B. Brandenburger, Robert B. Edenborg
  • Patent number: 4914139
    Abstract: An alkyd-type electrodepositable coating composition derived from the reaction of a base alkyd with ethylenically unsaturated monomers including an amine-functional monomer is provided with improved resistance to chipping by chemically incorporating in it by covalent bonding one or more chemical agents selected from the group of:(a) preformed elastomers having functional groups reactive with carboxyl or hydroxyl groups of acid and polyol alkyl precursors, and(b) an addition polymerizable monomer having primary and secondary ethylenic unsaturation.
    Type: Grant
    Filed: August 19, 1988
    Date of Patent: April 3, 1990
    Assignee: The Valspar Corporation
    Inventors: Philip J. Ruhoff, Rodney W. Stockstad, James A. Prevost, Larry B. Brandenburger, Robert B. Edenborg
  • Patent number: 4511692
    Abstract: A cationic electrodeposition composition comprising the reaction product of one or more base alkyds, containing unsaturation of the fatty acid chains to provide oxidative curing and one or more ethylenically unsaturated monomers, and one or more amine functional monomers, which are added to the base alkyd and polymerized. This composition provides a vehicle which is hydrolytically stable. Paints are prepared by the addition of conventional driers, pigments and solvents to the vehicle composition.
