Corrosion
Corrosion is an electrochemical process that occurs naturally. Electrolytes present on any unprotected metal surface can cause electrons to flow from a higher energy source or anode, to a lower energy source or cathode triggering oxidation or what we know as corrosion. Microscopic droplets of water that are present in the air at 70-85% relative humidity most commonly serve as the electrolyte and catalyst for corrosion.
How VCI Works?
Our Solution to corrosion? VCI
A microscopic thin layer of VCI on the surface of the metal inhibits the flow of electrons from anode to cathode thus slowing down the corrosion process. VCIs or Volatile Corrosion Inhibitors are safe specialized compounds that automatically release protective particles into the area around the packaged metal surface. These particles attach themselves to the metal surface and create a very thin protective layer (usually about 1 molecule in thickness). The term "Volatile Corrosion Inhibitor" is a bit misleading: VCIs are only volatile in the sense that they vaporize and release protective particles with the presence of an electrolyte, most notable being water.
