Stone chip protection of axle beams
Vehicle axle beams are exposed to high levels of stress from stone chipping and weathering and must therefore be protected against corrosion.
Challenge
- High stress due to stone chipping
- Stone impacts destroy primary corrosion protection layers and ecoat
- Spray water and salts lead to corrosion in the damaged areas
- The coating must withstand the elastic deformations even at low temperatures
Solution
- Stone chip protection through a water-based system that dries quickly at room temperature with high mechanical resistance
- Single-layer system with high yield
- Selective coating with staying power without running/sagging
- Excellent adhesion under mechanical stress, such as stone chipping
- Solid film after 30-60 minutes before installation
- High elasticity and elongation at break at low temperatures
