Protection of battery system screws
Moisture must not be allowed to reach the electrical components in battery systems, so the sealing points must be specially protected.
Challenge
- Bolting and thermal expansion destroys primary protective layer
- Corroding fasteners lead to leakage
- Multi-material mix promotes contact corrosion
Solution
- Wax-like anti-corrosion coating
- Barrier effect against corrosive media
- Creeping material that penetrates deeply
- Drying at room temperature
- Highest long-term flexibility under thermal and mechanical strain
Damaged and corroded underbody
Precise coating of screw heads on batteries
Benefit
- Reliable tightness of the connection
- No complex construction necessary
- Suitable for mixed construction
- Low material costs due to selective coating
- Easy loosening of the connections
- Easy removal of material residues
- Reparability of the battery system
- No energy costs during drying
