Patent number: 9683152Abstract: A two-component polyurethane adhesive is described. The polyurethane adhesive has high strength and extensibility, wherein the mechanical properties are only slightly dependent on the temperature. The polyurethane adhesive is suitable as a structural adhesive that is decomposed by heating in such a way that adhesive bonds can be undone in a temperature range of interest. The adhesive can include a triol, a diol, an alkoxylated aromatic diol, a polyamine, a polyisocyanate, and a polyurethane polymer having isocayanate groups in certain ratios.Type: GrantFiled: August 20, 2013Date of Patent: June 20, 2017Assignee: SIKA TECHNOLOGY AGInventors: Steffen Kelch, Wolfgang Roock, Florian Ittrich

Patent number: 9028640Abstract: A method for gluing of shaped bodies made of fiber composite compositions containing a plastic matrix KFZ with polyurethane compositions, the method including: a) application of IR radiation to a defined region of the shaped body of KFZ; b) application of a polyurethane composition to the defined region of the shaped body; c) bonding of the polyurethane composition on the defined region of the shaped body to a substrate; and d) curing of the polyurethane composition. The method is distinguishable by a rapid strengthening (early strength) of the polyurethane composition, so that the bond produced with its use can be machined or stressed already a short time after the application of the polyurethane composition.Type: GrantFiled: January 13, 2014Date of Patent: May 12, 2015Assignee: Sika Technology AGInventors: Martin Linnenbrink, Wolfgang Roock, Florian Ittrich
