Corrosion or rust on parts is a significant issue that automotive component manufacturers must anticipate, especially for long-duration sea shipments. The common problems associated with anti-corrosion measures typically include their consumption, application, and effectiveness.

In addition to using anti-corrosion agents, component manufacturers also employ volatile corrosion inhibitor (VCI) foils for double protection. These VCIs work by providing a thin protective layer to shield parts from water, air, and other potential contaminants that could cause rust. However, if any residual water is trapped within the VCI foils, it compromises the effectiveness of the VCI and leads to potential losses.

Success Story

One automotive component manufacturer once received a rust complaint from a customer. The rust was found upon receipt by an overseas customer, with an occurrence rate of over 20%. Upon investigation, trapped residual water was found beneath the VCI foil layer. This resulted in significant losses in terms of cost, time, and materials.

Eonchemicals provided a solution with Wedolit AS 2241, a corrosion inhibitor compatible with steel and many other metals and alloys, specifically designed to offer corrosion protection during sea transport and indoor storage. This product features and benefits include:

• Ideal for corrosion protection during sea transport
• Forms a uniform thin layer on the part’s surface
• Has a dewatering effect to eliminate residual water
• Protects parts from water, air, alkaline, and acidic contamination
• Easily cleaned with water-based cleaners or solvents
• Contains no volatile organic compounds, adding value for eco-friendly companies

SAfter conducting trials, the following data were obtained:

• Rust findings decreased to less than 1% from the previous 20%
• Anti-corrosion consumption reduced by up to 15%

Conclusion

Choosing the right anti-corrosion agent can protect parts from corrosion for an extended period during storage and sea transport, thereby enhancing the company’s competitiveness.
