Abstract:
An adhesive containing silicone, in the form of an adhesive compound which contains at least a first adhesive component and a second adhesive component containing silicone is provided. The second, silicon-laced adhesive component consists of a non-crosslinked polysiloxane. The kinematic viscosity of the non-crosslinked polysiloxane is at least 100,000 mm2/s and at most 10,000,000 mm2/s or that the molar mass of the non-crosslinked polysiloxane is less than 10,000 g/mol, and the second, silicone-containing adhesive component is microencapsulated. Alternatively it can be provided that the molar mass of the polysiloxane is at least 80,000 g/mol and at most 500,000 g/mol, or that the kinematic viscosity of the non-crosslinked polysiloxane is less than 100,000 mm2/s, and the second, silicone-containing adhesive component is microencapsulated.
