Volatile Corrosion Inhibitors

Our combined Vapour Phase (VPI) and Contact Inhibitors are unique multifunctional, multi-metal, anti corrosion solutions for sealed systems that are quick, simple and highly effective

With ordinary protective oils, all surfaces have to be completely coated to offer protection. This is often difficult to achieve in complex mechanisms such as engines or gearboxes and even when achievable the oil will drain away with a resulting loss of protection.

Volatile Corrosion Inhibitors, usually abbreviated to VCI or VPI, work by continuously releasing a powerful anticorrosion vapour. On contact with metal the vapour is absorbed onto the surface creating a film that will protect the metal from corrosion. The film is self-replenishing through further vapour release and is ideal for protecting difficult to reach or complex mechanisms.

VPI‘s can be applied through VPI oils or impregnated papers/polymers and can be used to enhance the performance of traditional temporary protective coatings. Provided that the component to be protected is in a sealed environment, and the correct weight of VCI is introduced, the protection period can be almost indefinite. For maximum performance from a VPI an enclosed system is recommended however typical treat rates will allow for some leakage.

By using a VPI the ease of use and resulting time and labour saving often more than offsets the entire cost of the VPI material.

Our vapour phase inhibitors have been formulated to offer reliable ‘best in class‘ performance. The key features are:

• • Combined vapour phase and contact inhibitor
• • Multi-metal protection
• • Low toxicity
• • Solvent free
• • Free of heavy metals, such as barium
• • Cost effective

When selecting a VPI, care should be taken to establish compatibility with paints, plastics and the metals to be protected.

Please contact us for advice on which VPI‘s to evaluate. We have the expertise to develop precisely the anti-corrosion package that will solve your corrosion problems.
