Protection of cavities in battery systems

Voids within battery systems are particularly susceptible to moisture and corrosion, as trapped fluids have difficulty escaping.

Application
Aluminium extruded profiles / Battery cavities
Exposure
Contact corrosion + thermal expansion
System
Water-based wax material
Curing
Drying at room temperature

Technical challenge

Moisture and condensation accumulate inside enclosed structures and promote corrosion in hard-to-reach areas.
