Publication number: 20100280167Abstract: 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: ApplicationFiled: November 21, 2008Publication date: November 4, 2010Applicant: SIKA TECHNOLOGY AGInventors: Karsten Frick, Jurgen Finter, Ulrich Gerber, Yves Meier, Jeannette Clifford

Publication number: 20100273005Abstract: The present invention relates to heat-curing epoxy resin compositions, which 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.Type: ApplicationFiled: November 14, 2008Publication date: October 28, 2010Applicant: SIKA TECHNOLOGY AGInventors: Andreas Kramer, Jurgen Finter, Karsten Frick, Urs Rheinegger, Jan Olaf Schulenburg
