The danger is in the air…

Corrosion is a numismatist’s worst nightmare. Even if your collection is well cared for and carefully stored, external influences can still damage the material of your valuable coins. This is because the air contains several substances which react with metals, leading to corrosion. Nitrous gases are one example, in addition to ozone and other corrosive gases, such as hydrogen sulphides, ammonia, carbonyl sulphide and chlorine compounds.

Problems with traditional methods of protecting coins

There are currently different ways for collectors to protect their coins. However, in comparison to INTERCEPT®, they all have disadvantages, e.g .:

Icons_traditionelle_Verfahren_ReinigungWith regard to regular cleaning, it is important to consider that all contact with the precious surface of the coin will wear it. So, less is more.
Icons_traditionelle_Verfahren_LackThis is also true for sealing coins with varnish, wax or oil. The inestimable risks involved in these processes mean they do more harm than good.

Functionality

The secret of INTERCEPT® is that corrosive gases are bonded before they are able to form a bond with the metal in the coin. This molecular process takes place immediately. Unlike other VCIs (volatile corrosion inhibitors), no layer forms on the surface of the coin. The highly porous copper particles embedded in the plastic compound bond to the damaging gas molecules in the air, locking them away permanently. The compound is never degassed and there is no build-up of environmentally harmful substances. Unfortunately, there is no process to restore corroded coins, which is all the more reason to recommend INTERCEPT®’s patented protection technology from the start.

Technology tried-and-tested in the industry

INTERCEPT® technology has been used in IT and heavy industry for 30 years and provides reliable protection for highly sensitive platinum, electronic components and car and aeroplane parts during storage and transit, as well as for packaging whole industrial machines.
Even museums and archives use this process: the Guggenheim Museum, the US National Archive and the British Royal Mint use it to protect coins, sculptures and other works of art.

Intercept Lagerung

INTERCEPT® is used in several industries, such as aerospace, defence, automotive, electronics, machine engineering, mining and oil and gas extraction.

Patented protection

The process has been proven effective in countless trials and lab tests according to DIN, EN, ISO and ASTM standards. The protection is so effective that even moisture penetration is rid of corrosive elements. The process was even recognised for its eco-friendliness by the German Federal Institute for Occupational Safety and Health. All INTERCEPT® products are non-toxic and completely recyclable.

FAQ

What materials does INTERCEPT® protect?
All ferrous and non-ferrous metals, i.e. all metals commonly used when minting coins. INTERCEPT® is not limited to one specific type of metal. Furthermore, its function is not based solely on protection against moisture. Instead, INTERCEPT® "neutralises" a variety of corrosive effects which affect all materials. Thus INTERCEPT® also protects against the aging of paper.

 

How does the material INTERCEPT® work?
The basis of INTERCEPT® technology is porous copper particles embedded into a polymer matrix. These particles react with the corrosive gases in the atmosphere and neutralise them. Even moisture which gets into the packaging is cleansed of corrosive elements. In contrast to conventional methods, therefore, no artificial atmosphere is created and corrosive impurities are instead removed naturally from the existing atmosphere. This means there is no emission of chemicals.

 

How long does INTERCEPT® remain effective?
INTERCEPT® is used for storage periods of up to 15 years. Depending on the location, the alloy concerned and the storage conditions, the product may remain effective for much longer. Currently, the longest experience of using INTERCEPT® has been since 1984, which allows competent forecasts for the duration of its effectiveness. Please note that repeated opening of an INTERCEPT® product reduces its duration of effectiveness. To extend the duration of effectiveness of INTERCEPT® products beyond the 15 years, it is recommended to close it immediately after use and to avoid frequent opening.

 

Can I tell when the effectiveness of the INTERCEPT® film has worn off?
Yes. When the potential of the INTERCEPT® film has been exhausted, the film will turn a dark grey/green colour (not the coins!). When this discolouration occurs, you should replace the INTERCEPT® product with a new one.

 

Can the INTERCEPT® film easily be recycled or disposed of?
Yes. INTERCEPT® fulfils all national and international recycling requirements for dyed and coloured plastics. All products should be disposed of according to the European waste code. It is not without reason that INTERCEPT® has been awarded for its eco-friendliness by the German Federal Institute for Occupational Safety and Health.

 

Is INTERCEPT® toxic?
The INTERCEPT® material gives off neither anions nor cations and contains no gas-emitting chemical substances. Therefore, the material is non-toxic. Consumption of the materials is not advisable, however.

 

Is INTERCEPT® a new process?
No. INTERCEPT® has been used in storage and the international transport of industrial goods since 1984. This technology was developed by Lucent Technologies Bell Laboratories (USA) and is patented worldwide.

 

Can I use INTERCEPT® products for coins that are already tarnished or for already aged documents?
Further corrosion will be prevented or significantly slowed down by the use of INTERCEPT®. However, already tarnished coins will not become 'untarnished'; the same applies to documents.

 

INTERCEPT® contains copper. Can this have a galvanic reaction if it comes into direct contact with other metals?
No. Through the permanent integration of the individual particles, a unique polymer matrix of the product, galvanic reactions are prevented even in the case of direct contact.
