Rust Preventative Case Study
WEDOLiT® reinforced both:quality and brand reputation
Global Automotive Parts Manufacturer Eliminates Corrosion with WEDOLiT®
A leading global automotive parts manufacturer processes a broad range of metals and alloys – including numerous steel grades – for automakers and their suppliers worldwide. The company faced recurring corrosion problems during long-distance transport and storage, particularly when goods were held in unheated warehouses at customer facilities.
THE CHALLENGE
Each shipment required reliable anti-corrosion protection across mixed metal types and extreme temperature ranges. However, the customer’s previous corrosion-preventive fluid often failed during overseas transport, causing visible rust, rework, and customer complaints. Additionally, the product contained a high concentration of volatile organic compounds (VOCs), conflicting with the company’s sustainability commitments.
SOLUTION
To address these challenges, the manufacturer conducted a full-scale trial with WEDOLiT® AN 7210, a high-technology corrosion inhibitor engineered for steel and mixed-metal components. The product provides:
Long-term protection for indoor storage and overseas shipments
Low-viscosity application, suitable for both spray and immersion processes
VOC-free formulation, supporting greener production environments
With WEDOLiT® AN 7210, the customer achieved consistent surface protection even under fluctuating climatic conditions – from humid maritime air to cold-storage handling.
RESULTS AT A GLANCE
- 10 % reduction in overall product consumption thanks to higher film efficiency
- Automated spray application, eliminating Manual labor and shortening production time
- Customer complaints reduced to below 2 %, with shipments arriving clean and corrosion-free
- Low-VOC formulation aligned the company’s operations with its global sustainability targets
- Improved workplace comfort through a low-odor, operator-friendly formula
The result was a smoother, more sustainable production line – and a corrosion protection strategy that reinforced both quality and brand reputation.
Steel is very fragile for recurring corrosion, particulaly when goods were held in unheated warehouses
