Thick-film protection: constant stone chipping
The underbody of a vehicle is the most corrosive area of a vehicle - especially in cold climates and near the sea, it has to withstand salt and constant to stone chipping in exposed areas.
Challenge
- Stone chips destroy primary corrosion protection and cathodic dip coating and lead to corrosion
- Constant exposure to stone chips and salt solutions
- Coating across various components in the assembled state
Solution
- Solid layer that absorbs stone chips through elastic and plastic deformation
- One-time application of a comparatively thin primer layer
- Water-based system, drys at room temperature
- Fast grip at room temperature
Chassis component selectively coated with thick-film protection
Selective coating of a chassis component with thick-film protection
Benefits
- Lower maintenance costs thanks to reliable corrosion and stone chip protection
- Low application costs
- Conserves resources
- No energy costs for drying
