Protection of battery system underbodies
Battery boxes are among the most sensitive areas in the vehicle. Their underbodies must therefore not only be protected from corrosion initiated by isolated stone chips, but also withstand constant stress.
Challenge
- Stone chips destroy primary corrosion protection, as well as the KTL, and lead to corrosion
- Continuous stress due to stone chips on the underbody
- After massive underbody damage, recoating in a workshop is necessary
Solution
- Solid layer that dampens stone impacts through elastic and plastic deformation
- One-time application of a comparatively thin protective layer
- Full stone chip protection
- Fast grip at room temperature
- Water-based system
Damaged and corroded underbody
UBS material tested for stone impact resistance with Multi Grit Tester 508 VDA
Benefit
- Lower maintenance costs
- Less application effort
- Conserves resources
- No energy costs during drying
- Repair possible
