Product information

tesa® 68105

High performance acrylic transfer tape



Product description

tesa® 68105 is a transparent transfer tape suitable for demanding lamination applications. The pure acrylic adhesive gives this product an excellent compatibility with printing inks, including conductive inks. The adhesive thickness offers the best compromise between adhesion on filmic polymers, high shear resistance and efficient processability. A moisture resistant liner gives this product good dimensional stability for die cutting processes.

tesa® 68105 features:

  • High shear strength under high temperature conditions
  • Easy repositioning during assembling processes
  • Excellent resistance against plasticisers
  • Low outgassing
  • Ageing resistance

Main applications

  • Lamination of overlays on touch switches
  • Fastening of printed nameplates and label stock
  • Assembly of all kind of filmic multilayer constructions
