Product Description

Product Description

ZERUST® Cor Tab® VCI Tablets are quick and easy to install. At first, simply place or sprinkle the VCI tablets in the desired area. Next, tightly seal the enclosure to trap the protective vapors inside.

Cor Tab® VCI Tablets diffuse invisible, odorless, and non-toxic ZERUST® Vapor Corrosion Inhibitor Technology (VCI). As a result, these VCI molecules settle onto exposed metal surfaces inside the enclosure. Once removed, the VCI will dissipate from the metal surfaces, allowing immediate use or further processing. Furthermore, Cor Tab® VCI Tablets protect ferrous and non-ferrous metals from corrosion for up to 6 months in a sealed enclosure.
