  • Impact strength improving agent for epoxy resin compositions
    Patent number: 9796809
    Abstract: The present invention relates to a butadiene/acrylonitrile copolymer CTBN, modified by epoxy solid resin and terminated by carboxyl groups, the terminal epoxy groups thereof also having optionally been reacted. A polymer of this type is used in particular as an impact strength improving agent in epoxy resin compositions and has proven to be particularly advantageous for gluing on or of metal surfaces. It results in a significant reduction of the infiltration with corrosion, which in turn ensures a long-lived adhesive bond.
    Type: Grant
    Filed: November 21, 2008
    Date of Patent: October 24, 2017
    Assignee: SIKA TECHNOLOGY AG
    Inventors: Karsten Frick, Jurgen Finter, Ulrich Gerber, Yves Meier, Jeannette Clifford
