The VCI principle by BRANOguard

VCI stands for Volatile Corrosion Inhibitor. Active VCI substances are compounds which, in addition to their corrosion-protection properties, also have vapour pressure characteristics. As the animation demonstrates, these active VCI substances vaporize out of the carrier material into which they have been integrated until a protective atmosphere has been built up inside the packaging.

These inhibitors accumulate on the surface of the metal and prevent the metal’s protective passive layer from deteriorating and allowing corrosion to take place.

Our BRANOrost VCI paper in particular offers exceptional protection - with absolutely no need for oil! Another highly recommended combination is our BRANOfol film plus our BRANOchips made out of VCI-emitting cellulose.

There are three methods for protecting your products against corrosion:

The coating method, (e.g. with an oil-based seal), the VCI principle (Volatile Corrosion Inhibitors) and the barrier-layer approach which includes the drying-agent methods.
