VCI corrosion protective film for steel, iron and non-ferrous metals Laminated with barrier foil material

Material / Characteristics

BRANOfol M 8.AL is a bluish transparent, nitrite-free special-polyethylene film with active VCI corrosion protection. The VCI film is laminated with a watervapour-proof barrier foil material. It is weldable and suitable for automatic packing as well as bag production.

The VCI-film inside constantly provides small amounts of active anticorrosion ingredients in the air of the packaging and also protects the upper metal surfaces, which are not in contact. The distance from the film to the metal depends on the packaging volume and the time permitted for a protecting atmosphere to build up. A rule of thumb: 10 cm.

The outer barrier foil material prevents the VCI-Inhibitor from escaping and keeps (new) humidity out.

Range of Protection

Steel, cast iron in contact, galvanized steel, nickel, aluminium, chromium, zinc, copper and copper base alloys can be reliably protected from corrosion. Test is recommended for cadmium and magnesium alloys.

Duration of protection: Depending on the climate condition and closeness of package, up to 36 month. If the exact application is known the time of protection can be adjusted.

Application

The packaging should form a closed space so that the best possible utilisation of VCI foil BRANOfol M 8.AL can be achieved. The packaging should be sealed closely. Water entering the packaged item should be avoided and has to be kept out.

Other basic rules for an ensured VCI protection to be followed: The surfaces to be protected must be dry and free from corrosion-stimulating residues, such as finger sweat and aggressive matter of washing agent, etc. Acids or strong bases interfere with the corrosion protection system. When in doubt, we recommend a compatibility test to be carried out.

The parts to be protected should not have any direct contact with wood or acidic materials. Atmospheric impurity as well as relative air humidity should be kept out of the package (e.g., no wood parts to be packed together).

Welding properties:
BRANOfol M 8.AL is processible in mild heat impulse and in separating-seam welding.

If strongly oiled parts are packed, then we recommend the application of nonprinted film, since the printing in contact with oil can possibly be solved.

BRANOfol-products are to be used as described above (packaging/ protection of certain kinds of metal pieces). Otherwise, no responsibility for caused damages can be taken.
