Z-Rust (VCI -Volatile Corrosion Inhibition)
The vapor corrosion inhibitor portion of Zerust ICT products is made of proprietary chemical formulations that are invisible, odorless, non-toxic, non-reactive, non-flammable and non-allergenic. These chemical formulations release a corrosion inhibiting vapor that diffuses throughout an enclosure that either contains ICT formulations or is made from ICT materials, and settles on exposed metal surfaces to form a microscopic corrosion inhibiting layer.
This protective layer will remain on the surface of the metal as long as there is no significant, continuous exchange of air within the enclosure.
The vapor diffusing properties of our corrosion inhibiting formulations offer an important advantage over conventional inhibitor coatings since the traces of these gas molecules penetrate into inaccessible crevices, gaps, and slots, reaching the surfaces of complex-shaped articles that are difficult to coat. They are adsorbed onto the surface of the metal to form a corrosion inhibiting protective layer that is just a few molecules thick. These “scavenging” chemicals react and neutralize the polluted air that may diffuse through the Zerust ICT material.
Zerust ICT products offer corrosion protection without having to be in direct contact with or coated onto the parts that are being protected. Metal parts merely need to be enclosed in or with a Zerust ICT product (where airflow is minimized) for protection to occur. With Zerust, it is no longer necessary to apply messy oils, greases and other corrosion protection compounds and incur the cost of their removal.
