Abstract: A control method for a hand-held power tool, in response to the actuation of a main switch of the hand-held power tool, carries out the following steps. An identification of transponders in the vicinity of the hand-held power tool is requested in that a transmitter transmits a radio signal. The identification of the at least one responding transponder is received by a receiver. The received identifications are compared to one or more identifications that are stored in a memory unit. The hand-held power tool is switched on if at least one of the identifications stored in the memory unit matches at least one of the received identifications.

Abstract: The present invention comprises methods for the pretreatment of substrates, including without limitation, metal or glass surfaces, with activators of reduced VOC content. Preferred embodiments of the invention comprise activators containing methyl acetate as a solvent, at least one adhesion promoter, and a luminescent agent responsive to light of specific wavelengths. In some embodiments, without limitation, an activator composition of reduced VOC content and also comprising a luminescent agent is applied to a substrate before application of additional adhesives or paints, and the substrate is examined under a controlled light source as required to excite the luminescent agent. The luminescent agent in the activator composition appears distinctly where the activator has been applied to the surface, allowing one to detect whether the activator has been properly applied.

Abstract: The invention relates to a primer composition, comprising at least one polyurethane prepolymer (A) with isocyanate terminal groups, at least one aliphatic polyisocyanate (B), at least one aromatic polyisocyanate (C) and at least one reaction product (D), which may be obtained from at least one epoxysilane and at least one aminosilane or from at least one epoxysilane and at least one mercaptosilane. The invention relates to the use of the primer composition as primer for adhesives, sealants and floor coatings.

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.
