Ferrogard corrosion protection papers act in accordance with the VCI principle (Volatile Corrosion Inhibitors) i.e. they release small amounts of volatile protective substances. A protective atmosphere is built up in packaging containing this paper providing reliable protection against corrosion for metal components. Ferrogard papers work on contact and from a distance and are nitrite-free. Unlike BRANOrost paper, Ferrogard paper qualities are not designed to handle the same mechanical stress.
