Corrosion protection for automotive suppliers – reliable, process-oriented, and OEM-compliant

Corrosion-resistant supplier parts – a must in modern vehicle production

Automotive suppliers provide structural, safety-critical, and visible components to the plants of major vehicle manufacturers. This also increases the demands placed on corrosion protection: Whether for raw parts, semi-finished products, or ready-to-install components— corrosion protection solutions for automotive suppliers must be precisely tailored to material, process, and logistical requirements.

PFINDER offers you reliable and practical products for corrosion protection in the automotive supply industry —whether as a temporary transport solution or a permanent coating.

Why Corrosion Protection Is Critical for Suppliers

In the automotive industry , components must not only be manufactured with precision but also transported to the OEM with corrosion protection —often over long distances, involving temporary storage, packaging, or CKD shipping.

Untreated or inadequately protected metal surfaces corrode quickly—due to humidity, temperature fluctuations, condensation, or salt particles. In addition to purely functional damage, visual quality can also be compromised—which is particularly critical for visible parts. For ready-to-install sheet metal components that are integrated into the body, the OEM’s final corrosion requirements apply.

Professional corrosion protection for automotive suppliers ensures:

The quality of the delivered components
Compliance with OEM specifications
Seamless integration into the production process
The efficient operation of your supply chain

Common challenges in the supply chain

Protection of uncoated metal parts (e.g., steel, galvanized parts, aluminum)
Components that will later be welded, bonded, or painted
Protection required during transport, temporary storage, or export
Components with complex geometries, edges, or holes
Corrosion protection and protection against stone chips

Our Solutions for Automotive Suppliers

PFINDER offers modular products for temporary or long-term corrosion protection that can be combined depending on the component type, OEM requirements, and process structure.

Temporary corrosion protection – reliable protection during transport and storage

For many automotive suppliers, the temporary corrosion protection is the ideal solution: Components are protected - but the protection can be easily removed later, e.g., before assembly or painting at the OEM.

Advantages:

Easy to remove without leaving residues
Application by spraying, wiping, or dipping
Transparent and pigmented variants
Protection duration ranging from days to months (depending on the product)

Long-term corrosion protection for functional components

For components particularly susceptible to corrosion or products that are integrated into end systems (e.g., as structurally critical parts), PFINDER offers robust coating systems —including paint-like coatings or preservative layers based on wax or oil.

Properties:

Resistant to moisture, salt, and abrasion
Can be applied directly to cleaned surfaces
Products with OEM approvals available
Selectively applicable stone chip protection
Partially electrically insulating

Cavity & Edge Sealing

Even in supplier parts, cavities, flanged edges, or open joints can be susceptible to corrosion - especially in components made up of multiple sheet metal parts. PFINDER offers suitable cavity waxes that can be applied precisely even on small components and reliably seal deep areas. The components, sealed according to OEM specifications, can then be directly integrated into the overall body structure.

Integration into your process – flexible and cost-effective

Our corrosion protection products can be easily integrated into your production or packaging lines. Application can be:

Be performed manually: e.g., with a spray can, lance, brush, or sponge
Be semi-automated: e.g., stationary spray systems
Fully automated: e.g., via robots or rotating nozzle heads for large-scale production

We advise you on selecting the appropriate application method - tailored to production volumes, component geometry, and the desired duration of protection.

Practical

Corrosion protection in cavities
The hollow-space structures in vehicle bodies are efficient designs that offer high rigidity and play a key role in crash protection; therefore, they must be protected against corrosion, especially in humid conditions.
