How does VCI compare to desiccants in preventing corrosion?

Alex Todd

Valdamark VCI technology is an active corrosion protection method that involves the release of VCI molecules into the environment.

VCI molecules are invisible, odourless, and non-toxic, making them safe for use in a variety of settings.

VCI molecules are released into the air inside a Valdamark bag. These VCI molecules will continue to be released until the air inside the bag is completely saturated. VCI molecules will then attach themselves to all metal surfaces inside the bag, forming a rust-protective layer. This layer of VCI molecules prevents electrochemical reactions that could cause corrosion. As a result, the use of a Valdamark VCI bag can effectively prevent rust and corrosion on all metal surfaces.

Desiccants are often used as a passive form of corrosion protection, where they absorb moisture from the surrounding atmosphere. This reduction in ambient humidity can prevent the formation of electrolytes on metal surfaces that might otherwise activate electrochemical corrosion reactions. However, desiccants have a very finite limit to the maximum amount of water they can absorb. Once this is exceeded, desiccants cease to provide any further protection and may in fact leak moisture back into their surroundings
