  • One-component epoxy-modified polyurethane and/or polyurea adhesives having high elongation and excellent thermal stability, and assembly processes using same
    Patent number: 10815405
    Abstract: A one-component epoxy-modified polyurethane and/or urea adhesive includes very high levels of reactive urethane group- and/or urea group-containing tougheners, an epoxy resin and epoxy hardener. These adhesives are formulated to cure at high temperatures and surprisingly provide high elongations, excellent thermal stability and good adhesive properties.

  • TOUGHENED EXPANDABLE EPOXY RESINS FOR STIFFENING AND ENERGY DISSIPATION IN AUTOMOTIVE CAVITIES
    Publication number: 20100028651
    Abstract: Expanded, toughened structural adhesives form stiffening materials for vehicular panels and bodyshell structures. The toughened structural adhesive contains an epoxy resin, a rubber, an elastomeric toughener, a curing agent, and an expanding agent. The expanded structural adhesive greatly increases the amount of energy absorbed by the panel or bodyshell structure during an impact. A blowing agent combination of a chemical blowing agent with expandable microballoons provides for especially good energy absorption.
