Product description
tesa® 64993 is a white double-sided adhesive tape consisting of a conformable PP-film backing and a tackified acrylic adhesive. With a thickness of 240 µm it is perfectly suitable to mount automotive exterior and interior 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. This leads also to an excellent splintering protection performance.
Main features:
- Excellent combination of a high initial tack and adhesion level
- Superior wet-out performance
- High initial adhesion to ABS and ABS/PC
- Excellent gap filling
- Conformable and robust PP-film backing
- Good temperature resistance
- Excellent converting properties, especially with the humidity resistant PE-coated paper liner (PV4)
Main applications
tesa® 64993 is suitable for mounting automotive exterior and interior mirrors.
Example applications are:
- Mounting of non-heated automotive exterior and interior mirror onto the base plate
- Mounting of automotive exterior mirror with heating element onto the base plate
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.
