Silicone-containing pressure-sensitive adhesive and pressure-sensitive adhesive products such as an adhesive tape or a label, and process for producing same

An adhesive comprising a first adhesive component and a second, silicone-containing adhesive component, wherein the second, silicon-containing adhesive component consists of a non-crosslinked polysiloxane,

• wherein the molar mass of the non-crosslinked 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, wherein the second, silicone-containing adhesive component is microencapsulated.

A process for manufacturing a pressure-sensitive adhesive product comprising a band-shaped carrier upon which at least on one side a pressure-sensitive adhesive in the form of an adhesive composition is applied, the process comprising:

• providing a base product having a width in a range from 100 mm to 2500 mm, and cutting or stamping the base product with a cutting tool, wherein the cutting tool comes into direct contact on cutting edges with the pressure-sensitive adhesive, wherein the adhesive composition comprises a first adhesive component and a second, silicone-containing adhesive component, the second, silicon-containing adhesive component consisting of a non-crosslinked polysiloxane, wherein the non-crosslinked polysiloxane has one of the following two features:
• (1) 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, wherein the second, silicone-containing adhesive component is microencapsulated;
• (2) the molar mass of the non-crosslinked 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, wherein the second, silicone-containing adhesive component is microencapsulated.
