tesa® 66108

0.8 mm double-sided PE foam tape for mounting of automotive mirrors



Product description

tesa® 66108 is a double-sided adhesive tape consisting of a PE foam backing and a tackified acrylic adhesive. With a thickness of 0.8 mm it is perfectly suitable to mount automotive exterior mirrors with or without heating element onto the base plate.
The tackified acrylic adhesive features an high initial and ultimate adhesion strength especially to ABS and ABS/PC and a good temperature resistance.

Due to the high conformability the tape ensures a superior wet out and compensates design tolerances leading to an reliable bond especially for electrochromic mirrors with higher weight and mirrors of light and heavy trucks and bus bigger in size and with increased curvature. This leads also to an excellent performance in splintering protection and cold shock resistance.

Main features
  • High initial adhesive strength
  • Excellent cold shock resistance
  • Superior wet-out performance
  • Conformable PE foam backing to compensate design tolerance
  • Excellent splintering protection
  • Good temperature resistance performance
  • Excellent converting property
  • UV resistant

Main applications

tesa® 66108 is suitable for mounting automotive exterior mirrors with or without heating element onto the base plate.

Example applications are:
  • Passenger car mirror with electrochromic mirror glass
  • Light and heavy truck and bus mirrors with bigger size and increased curvature

To ensure the highest performance possible, our aim is to fully understand your application (including the substrates involved) in order to provide the right product recommendation.
