​What is VCI ?

VCI stands for Volatile Corrosion Inhibitor. It can volatilize into a gas that inhibits corrosion at room temperature of a metal object and forms a protective molecular layer on the metal surface. The protective film layer prevents moisture, oxygen and other gases from contacting the metal surface and inhibits electrochemical reactions that cause metal corrosion, thus achieving the purpose of rust prevention.
