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

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, silicone-containing adhesive component consisting of a non-crosslinked polysiloxane, without microencapsulation;
• wherein the second, silicone-containing adhesive component has a molar mass of at least 100,000 g/mol and at most 500,000 g/mol;
• whereby the molar mass is calculated using the formula:
• Mn=[(log v-1)/0.01231]2,
• wherein v is the numerical value of a kinematic viscosity in mm2/s at 25° C. from measurements of the viscosity in accordance with DIN 53019-1:2008-09, and Mn is the numerical average of the molar mass,
• whereby the bond strength of the adhesive on steel lies in a range between 5 N/cm and 10 N/cm measured according to DIN EN 1939:2003-12.
