Maintaining and protecting the underbody are essential factors in extending a vehicle’s service life and ensuring its safety. In addition to stone chip protection coatings, wax-based corrosion protection materials are used, which can be applied to nearly any surface—including oily ones—as well as to various component combinations and their fasteners. Their primary purpose is to protect against corrosion. Since stone chips can also occur in these areas, a thick-film, wax-based protective coating is recommended. The self-healing properties of these protective materials are particularly outstanding. They not only provide a mechanical and chemical barrier but also repair themselves when damaged. This is especially important for protecting the underbody from corrosion caused by stone chips and other mechanical influences over the long term.
CHALLENGE
Stone chips and mechanical stress can damage even the most robust protective coatings, allowing corrosive elements such as water and salt to penetrate. This leads to corrosion and poses a significant challenge, especially in regions with high mechanical stress or heavy road salt exposure. It is therefore necessary to apply appropriate protection to vehicles that are not adequately protected by the manufacturer before they are used in these regions.
SOLUTION
PFINDER’s self-healing products are specialized materials used in underbody protection that, thanks to their unique physical properties, are capable of automatically repairing damage to the protective layer. These self-healing materials offer several advantages:
These innovative self-healing products are particularly well-suited for the underbody of vehicles operated in regions with high mechanical and corrosive stress. They are applied to specific areas of the underbody where protection requirements are especially high. They can be applied both during production and as retrofit solutions, ensuring flexible use.
Overall, PFINDER’s self-healing products offer comprehensive protection for vehicle underbodies. Their ability to absorb mechanical damage while simultaneously repairing themselves makes them an ideal solution for the diverse challenges faced by a vehicle’s underbody. Through the innovative combination of self-healing and residual protection, these products play a key role in extending the vehicle’s service life and preserving its value.
The underbody combines components with a wide variety of surfaces, such as galvanized screws in an aluminum housing. When applying post-preservation treatment for specific regions, contaminants are already present on the surface. The wax-like materials adhere across all components and seep into the gaps.
