VCI Powder

VCI Powder VCI Powder 1 VCI Powder 2 VCI Powder 3

VCI Powder (Volatile Corrosion Inhibitor Powder) is a Vapor phase Corrosion Inhibitor for corrosion protection of ferrous and non-ferrous metals. It provides an extremely efficient dry method to protect metals within an enclosed space. The VCI vaporizes and then adsorbs on all metal surfaces, reaching every part of the metal surface, including recessed areas and interior cavities.

It is off-white in color and in powder form.
