Protection of battery system underbodies
The underbodies of battery systems are constantly exposed to mechanical stress, moisture, and road salt.
- Application
- Lower shield battery system
- Exposure
- Stone Chipping & Corrosion
- System
- Water-Based Underbody Protection System
- Curing
- Tack-Free at Ambient Temperature
Technical challenge
Stone chips and corrosive substances damage surface coatings and increase the susceptibility of components to corrosion.

UBS material tested for stone chip resistance using the Multi Grit Tester 508 VDA
Solution Concept

Left: Paint damage caused by stone chips; right: Protected surface
Use of water-based UBS and thick-film systems with high mechanical strength.
