Corrosion protection in cavities
The hollow-space structures in vehicle bodies are efficient designs that offer high rigidity and contribute to crash safety, but they are particularly susceptible to corrosion because moisture can penetrate them and has difficulty escaping. Without appropriate protective measures, corrosion often goes undetected for a long time.
- Application
- Vehicle Body Cavities
- Exposure
- Moisture, Salt & Vibration
- System
- Wax-Based Cavity Preservation System
- Curing
- Air-Drying / Permanently Flexible
Technical challenge
Moisture and condensation accumulate in hard-to-reach areas. At the same time, applying a uniform coating to these areas is technically challenging, as they are often not directly accessible.
Sealed gap in the cavity
Solution Concept
Wax-based, flowable corrosion protection systems are used. These systems spread even in complex geometries and reliably reach areas that are difficult to access.
Sealed gap in the absence of KTL
