Protection of cavities in battery systems
In battery systems, aluminum extrusions are needed for battery stiffness and are often combined with other materials, which can lead to accelerated corrosion.
Challenge
- Aluminum extrusion combined with other materials
- Material erosion due to galvanic corrosion / contact corrosion
- Different thermal expansions
Solution
- Aqueous wax material drying at room temperature
- Barrier effect against corrosive media
- Low viscosity material creeps into gaps between components
- Material is flexible under thermal and mechanical strain
- Assurance of coating (quantity & quality) by simulation
Damaged and corroded underbody
Protection of a cavity in extruded aluminum profile
Benefit
- Enables mixed construction methods and thus more flexibility in design
- Longer service life and component safety
- Energy and cost efficient solution
- Reduction of costs in the development process through simulation of wax application
- No energy costs during drying
