  • Patent number: 11198754
    Abstract: Heat-curing epoxy resin compositions are characterized by high impact strength, good storage stability, and a low curing temperature. The epoxy resin compositions are suitable for use as a construction shell adhesive and for producing structural foams. They can already be cured in so-called bottom-baking conditions. Furthermore, it has been found that the use of an accelerator of the formula (Ia) or (Ib) results in an increase of the impact strength of heat-curing 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.

  • Publication number: 20150252165
    Abstract: The present invention relates to expandable compositions in the form of granular materials that are based on epoxy resins with a content of binders and curing agents for curing the epoxy resin. Corresponding compositions can be readily introduced into hollow bodies, for example, into sticks or roof supports and expanded to a foam by heating the composition and cured. This results in hollow bodies filled with foam that are distinguished by significantly improved mechanical properties compared to comparable hollow bodies without a foam filling. At the same time, the granular materials according to the invention can be very readily processed without a complex and expensive two-component injection-molding process being necessary.
