tesa® 64908

Product description

tesa® 64908 is a double-sided adhesive tape consisting of a conformable black PE foam backing and a LSE adhesive. With a thickness of 0.8 mm, it is suitable for mounting of small parts, like emblems and entry trims.

The LSE adhesive features a high initial adhesion to LSE clear coats and LSE plastics such as PP and PP/EPDM, and MSE plastics like ABS and PC without utilizing primer. It reaches a high level of peel adhesion level right after application. Additionally, it even provides near to peak performance at an application temperature as low as 5°C. The impressive cold shock performance is due to the damping properties of the PE foam backing even at temperatures below -40°C.

Due to its high conformability, the tape ensures a good wet out and secure bonding including on uneven surfaces and compensates for design tolerances. The PE foam backing also provides non-sticky edges resulting in excellent converting properties, e.g. for die cutting. Additionally, the tape combines high cohesive strength with a comparatively low density contributing positively to a light weight design.

Main features:
  • High initial adhesion to LSE and MSE surfaces without primer
  • Near to peak peel adhesion level right after application
  • Good performance at an application temperature as low as 5°C
  • Conformable foam backing to compensate design tolerances or uneven surfaces
  • Reliable performance at higher temperatures
  • Excellent converting properties

LSE: low surface energy
MSE: medium surface energy

Application Fields

tesa® 64908 is suitable for mounting a wide range of small exterior and interior trims and parts.

Example applications are:
  • Small decorative exterior and interior trims
  • Emblems
  • Lettering such as single letters for classification of car models or engine data

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
