FAQ
What are the best corrosion protection coatings for automotive underbody components exposed to road salt?
Automotive underbody components are exposed to highly aggressive conditions such as road salt, moisture and stone chipping. To ensure long-term corrosion protection, several coating solutions are commonly used, often in combination.
Zinc-based coatings, such as zinc-nickel plating, provide sacrificial corrosion protection, while cataphoretic painting (KTL) and powder coating act as durable barrier layers. KTL is particularly effective for complex geometries.
For the most demanding applications, duplex systems combining zinc-based coatings with KTL or powder paint offer enhanced durability and extended service life. The final solution is defined according to component design, exposure level and OEM specifications.
Do your E-coat (KTL) services meet automotive OEM specifications for salt spray resistance and adhesion?
Yes. Our E-coat (KTL) processes are qualified to meet major automotive OEM specifications for salt spray resistance and coating adhesion.
Performance is validated through standardized and OEM-specific tests, supported by controlled pretreatment, stable process parameters and adapted coating thickness. All treatments are regularly tested and fully traceable, in line with automotive quality requirements.
Can you provide Zinc-Nickel plating as a cadmium replacement for brake system parts in trucks?
Yes. Zinc-Nickel electroplating is a proven cadmium replacement for brake system components in trucks and commercial vehicles.
It offers high corrosion resistance and stable performance in severe environments while meeting regulatory requirements such as REACH. The coating system is defined according to component design and applicable specifications.
What surface preparation and pretreatment do you recommend before powder coating aluminum motorbike frames for optimal durability?
For aluminum motorbike frames, proper surface preparation is essential to ensure corrosion resistance and durable powder coating adhesion.
Pretreatment typically includes cleaning and surface activation, followed by a conversion treatment based on chromium-free or trivalent chromium (Cr³⁺) passivation. The final pretreatment sequence is defined according to the aluminum alloy, exposure conditions and durability requirements.
How do your duplex coating systems (e.g., plating + E-coat) improve the lifespan of heavy vehicle chassis in harsh environments?
Duplex coating systems combine a metallic coating (such as zinc or zinc-nickel) with an organic topcoat like E-coat (KTL) to improve corrosion protection in harsh environments.
The metallic layer provides sacrificial protection, while the E-coat acts as a durable barrier against moisture and road salt, even on complex geometries. This synergy significantly extends the service life of heavy vehicle chassis. The final system is defined according to design and performance requirements.
