  • Epoxy-paste adhesives resistant to wash-off
    Patent number: 9133375
    Abstract: This invention relates to compositions useful as adhesives and more particularly to the preparation of heat-curable epoxy-based adhesive compositions that are resistant to being washed off substrate surfaces prior to being cured. The incorporation of a solid diene-based rubber, in particular an acrylonitrile-butadiene copolymer rubber having a relatively high Mooney viscosity, significantly enhances the wash-off resistance of the adhesive, while still allowing the adhesive to be readily dispensed by pumping under high shear conditions.
    Type: Grant
    Filed: April 29, 2010
    Date of Patent: September 15, 2015
    Assignee: Henkel AG & Co. KGaA
    Inventors: David Sturgill, Scott L. Hartsell, Jeng-Li Liang, Rajat K. Agarwal
