Okay kiddo, let me explain what is a volatile corrosion inhibitor (VCI) in a way that you can understand.
Do you remember when we went to the park and saw a metal bench? Metal can get rusty and corroded when it comes in contact with oxygen and water. This is called corrosion. Corrosion can make metal weak and eventually break.
So, some smart people invented something called VCI. VCI is a special chemical that can protect metal from rust and corrosion. It works by releasing special gases that surround the metal and prevent oxygen and water from reaching it. Think of it as a bubble wrap around metal that protects it from outside harm.
When you buy something that’s wrapped in special plastic, like your toys or a new bike, you might notice a strange smell. That smell is the VCI gas being released from the plastic. It's harmless to you, and it doesn't harm the metal either. It just makes sure that the metal stays shiny and strong for a very long time.
So, the next time you see a metal object or even your bicycle, remember that it can be protected by VCI like a magic bubble wrap.
