  • Patent number: 6696124
    Abstract: An adhesive compound is described that is formed using a specific adhesive system. Due to the specific adhesive system the disconnecting of the adhesive compound is considerably eased, which, in particular, is of great benefit for the quick removal of plastic windows in case of emergency. The specific properties of the adhesive compound are based on its specific structure. In the middle of the compound between the substrates a specific parting layer is installed by which the two substrates can be disconnected easily. The parting layer preferably is an elastomer that has an extremely high tenacity and an elongation at rupture of 500% up to more than 1500% and that shows a good adherence to the assembly adhesive so that the removal can be performed by stretching the parting layer whereby it constricts and thereby peels off from the adhesive.
