Corrosion Intercept®

Corrosion Intercept is a PE-film with embedded highly reactive copper particles. All kinds of gases witch can corrode copper are absorbed by the film. Metals, wrapped in Corrosion Intercept, will perfectly protected from these kinds of gases. The film is translucent so the content of the bags remains easy to identify.

CI is available as:

• Corrosion Intercept® bags, especially used for coins, CD's, jewellery, photos and film
• Corrosion Intercept® film, e.g. to wrap textiles, paintings and books
• Corrosion Intercept® stretch film, e.g. to wrap steel products
• Corrosion Intercept® foam, for filtering units, showcases or packaging

The use of Corrosion Intercept® protects from three kinds of corrosion: "atmospheric" corrosion (corrosive gases) "galvanic" corrosion (electromechanically processes of two different metals) "biological" corrosion (dust and fungi) It protects: metals: copper, silver, brass, iron and nonferrous metals CD's photos and films textiles (e.g. with silver threads...) paintings (protection of pigments and silver leaf from hydrogen sulphide)

Advantages of Corrosion Intercept:

• Protects, but remains translucent (picture to the right)
• Reacts with the corrosive gases and binds them permanently (gases like ozone, hydrogen sulphide and other sulphur-compounds, formaldehyde, chlorine-compounds, gaseous acids et al.)
• Creates an impermeable barrier for corrosive gases, fungi and bacteria.
• Intercept is not a VCI (Volatile Corrosion Inhibitor), it doesn't liberate volatile chemicals
• Corroseion Intercept leaves no residue on the wrapped objects
• Long term stablity: Intercept with a thickness of 25 µ protects at least ten years
• Integrated saturation indicator
• Environmentally safe and recyclable
• RoHS-compliant

These coins were stored for ten years in a usual album in a sulphurous athmosphere.		The same coins stored in an album that was laid out with Intercept - the coins don't show any trace of corrosion.

Further information:

• Pamela B. Hatchfield: Pollutants in the Museum Environment, London 2002, S. 123-124: describes tests of Corrosion Intercept in comparision with similar materials.
• Certificate concerning a silver plated object, exposed to hydrogen sulphide at various levels relative humidity. Comparatve test of different types of packaging (Comptrade = Corrosion Intercept Film)

Corrosion Intercept® bags

With or without clip, various sizes, for storage of coins, medals silverware and jewellery.
Since Corrosion Intercept® Film is half transparent you can identify the content without opening the bag.

Alternatively we offer bags made of one side CI-film, one side clear film. Protection will be a bit less than inside bags made of both sides CI-film, but visibility is much better.

Other sizes of bags can be custom made. For large objects we recommend the beautiful "Intercept-Protector"-Pouches which simultaneously offer mechanical protection.

Corrosion Intercept® CD-sleeves

Corrosion Intercept® Film

For protective packing of larger objects. Corrosion Intercept Film can be sealed with any table top or hand held impulse sealer,
so each object can be packed individually. Since the film is translucent the content and the accession number still can be identified. We also custom make bags according to your needs.

Corrosion Intercept® Foam

With the help of CORROSION-INTERCEPT ® filter pads, corrosive gases inside a display case or storage cabinet can be passively reduced as well neutralised in their damaging effects on the object.   With this method it is irrelevant whether the corrosive gases derive from the environment, e.g. the packaging, or the object material itself. The protective impact is not influenced by relative humidity. It is continuously active through the full spectrum of climate parameters. These filters considerably reduce contaminants attacking metals like sulphur dioxide, H2S and other pollutants. They will absorb dust, pollutants and others harmful substances.
