Corrosion protection through a physical barrier – visibly effective.
PFINDER provides long-lasting protection for surfaces—with custom-formulated waxes, varnishes, and protective coatings.
Corrosion is a natural, electrochemical process that degrades metallic materials and, in the worst case, compromises the function or safety of a component. Corrosion protection aims to slow down or completely prevent this process. By using suitable anti-corrosion materials, intelligent material selection, and state-of-the-art technologies, the service life of metal components can be significantly extended. Whether in automotive engineering, industry, or manufacturing: corrosion protection is indispensable wherever metals such as steel or aluminum are used.
If the barrier works, the material is protected.
Corrosion develops through contact with water, oxygen, and salt. PFINDER products take action before damage occurs: Our physical barriers interrupt contact between the metal and its surroundings —providing a lasting, application-specific, and safe solution.
- No chance for rust thanks to dense protective layers
- Customized solutions for cavities, underbody, and more
- Effective even under mechanical stress, heat, and moisture
- Long-lasting, removable without leaving residue, or permanent

Corrosion protection tailored to the material
Anti-corrosion materials and their applications
Depending on the application, different anti-corrosion materials are used:
- Cavity protection wax: Protection of hard-to-reach areas in the bodywork
- Underbody protection: Protects vehicles from stone chips, moisture, and salt
- Paint-like coatings: Provide a paint-like film and functional protection
- Temporary corrosion protection: For transport and storage
- Cleaners: Removal of wax residues (e.g., overspray) and temporary protective coatings
All these products serve one purpose: to effectively protect metal from corrosion —regardless of the application.
Corrosion Protection in Action
A modern vehicle consists of hundreds of metal components, many of which are installed on the exterior or in cavities. Without effective corrosion protection, rust would cause visible and invisible damage within a short period of time.
But not only in the automotive industry, but also in areas such as:
- All types of vehicle manufacturing (buses, trucks, ACE)
- Aerospace technology
- Rail vehicles
- Power plants
- Mechanical engineering
- Agriculture
Protection against corrosion is crucial for the functional reliability and service life of the products.
The mechanism behind the protection
Corrosion protection is based on isolation.
Our coatings block the path of corrosive media to the metal surface. They form a continuous, adhesive, flexible layer that prevents both water and salt from penetrating—even in the event of minor damage.

Which product provides the best protection for your surface?
Choosing the right corrosion protection is always a case-by-case decision: Geometry, material, stress, and application method determine whether cavity wax, underbody protection, paint-like coatings, or temporary protection is the best solution. Our experts analyze your components and processes, work with you to define the protection requirements, and recommend the right product—including testing at our technical center and support through to series production, if desired.
