Universal cavity and underbody protection

Vehicle cavities and underbodies are the areas most exposed to moisture and stone chipping and therefore require long-term flexible protection against corrosion.

Challenge

  • During the cathodic dip coating (e-coat) process, incomplete coating may occur in the cavity
  • Not all components of the underbody are sufficiently protected against corrosion or are damaged by stone chipping
  • Moisture and salt then lead to corrosion in cavities and in damaged areas

Solution

  • Universally applicable anti-corrosion wax for cavities and the underbody.
  • Flowable material closes gaps and small holes, forming a barrier against water and salt and thus preventing corrosion
  • Use of an air-drying system with a high yield

Benefit

  • High level of safety due to flexible long-term corrosion protection
  • Easy re-pasivation due to high compatibility
  • Drying of the system to a film without additional energy input
