How VAPORTEC VCI's work:


Vapour Corrosion Inhibitors (VCI's) are similar to organic adsorption type inhibitors and also possess a high vapour pressure. As a consequence, these VCI's can be used to inhibit atmospheric corrosion of metals. A concentration of VCI is placed in the vicinity of the metal to be protected.

The VCI sublimes (i.e. changes from a solid phase to a gaseous phase, without becoming a liquid) and the gaseous molecules of the VCI concentrate near the metal surface. These gaseous molecules then adsorb onto the metal surface forming a mono-molecular layer of corrosion protection.

For a compound to be classified as a VCI, it must possess two basic properties, i.e.

(i) it must be volatile and
(ii) the vapour alone must be able to retard the corrosion rate.

VCI's are specific, in terms of the type of the metal or alloy, environmental conditions, temperature and concentration. It is important to always use VCI's in excess as in some cases to little inhibitor can actually cause accelerated corrosion. VCI's are available in a number of different forms and are designed to meet specific applications.

Vaportec VCI's are blends of special compounds having differential vapour pressures. This ensures quick and long lasting passivation of all metals.
