1. Product overview
tesa® 66108 is a 0.8 mm double-sided PE foam tape with tackified acrylic adhesive, developed for mounting automotive exterior mirrors. Its conformable foam backing ensures excellent wet-out, compensates for design tolerances, and provides secure bonding even with heavy, large, or curved mirrors. The tape offers high initial adhesion, strong splintering protection, and reliable temperature and UV resistance, making it suitable for demanding automotive applications.
2. Applications
Mounting passenger car exterior mirrors, including electrochromic mirrors
Fixing light and heavy truck or bus mirrors with larger sizes or increased curvature
Suitable for both heated and non-heated mirror assemblies
