"VCI" STANDS FOR VOLATILE CORROSION INHIBITOR

The chemicals in VCI products are volatile.When metals are wrapped or packaged inVCI, the chemicals volatilize in the packaging

environment, forming a protective molecular layer on the surface of the metal. This protective layer serves as a larrier,preventing moisture,salt,dirt,oxygen, and other corrosion causing materials from depositing directly on the metal and causing rust and corrosion.

HOW VCI WORKS

Corrosion inhibitor compounds vaporize from the paper or film.They are attracted to the charged surface of the metal by virtue of their polar orientation.

The VCI molecules align on the surface of the metal to depth of 3 to 5 molecules. This layer of molecules passivates the charged surface and creates a barrier that prevents oxidation. The corrosion cell(the flow of electrons in the metal and the flow of ions in 

the electrolytic surface layer) is unable to establish itself.Corrosion is halted.

AIRTIGHT PACKING IS NOT REQUIRED!

Simply store or ship metal parts in VCIpackaging. When the parts are unwrapped,the protective layer immediately begins to dissipate. The metal parts are clean,corrosion-free and ready to use. No washing,dipping or cleaning is necessary.

The VCI molecules migrate into recesses and hard to reach on even the most complex shapes. The molecules build up on the metal

surface until a continuous barrier has formed on the metal part.
