Abstract

The invention relates to a one-component epoxy resin adhesive which is elasticated with silicone rubber and whose open joint time is adaptable to whichever production process it is being used in by the concentration of UV initiator and/or the duration and/or intensity of UV activation and which is therefore particularly suitable for automatable manufacturing processes, since the workpieces after initial fixing require no additional mounts even during thermal aftercuring. This adhesive is preferentially suitable for the extensive adhesive bonding of permanent magnets, such as in the assembly of a permasyn motor, for example.
