How It Works:

Developed by Lucent Bell Labs to solve problems they were experiencing with Tarnish and Corrosion. The Intercept Technology™ is a revolutionary product reacting solid state reactive materials into a polymer matrix. These reactive materials react with and neutralize all corrosive gases that contact the film. Protection against corrosive gases is 10 years per mil of Intercept material. Intercept™ protects Ferrous and non-Ferrous Metals as well as preventing Galvanic Corrosion.

Metals corrode (tarnish) by reaction with common gases in the atmosphere. These corrosive gases react with both Ferrous (Iron based) and Non-Ferrous metals, however these gases are the primary cause for tarnish and corrosion of Non-Ferrous metal (such as Silver, Gold, Tin, Copper, Brass, etc).

Why It's Better:

Intercept™ provides the best protection against tarnish and corrosion causing gasses: Reacts with and permanently neutralizes corrosive gases Can Provide corrosion protection for up to 10 years per mil of Intercept™ material Clean and Non-abrasive, will not scratch items it protects (unlike Charcoal based products) Leaves no detectable deposit on any product it protects (unlike VCI's) Will not harm gemstones like pearls, opals, emeralds, amber, onyx, etc. Cleanses trapped air of corrosive gases Temperature and humidity independent Provides cost savings by eliminating secondary packaging and cleaning operations often required with VCI protection, Charcoal protection, or no protection Acts as a passive Bactericide and Mildewcide Effective against Galvanic coupling (corrosion between joined dissimilar metals) Eliminates the need for storage in inert atmospheres Environmentally friendly with substantially reduced landfill time (breaking down into Polymer dust) and fully recyclable (meeting tough German recycling laws)

Intercept Technology™ provides effective tarnish & corrosion prevention for the following materials:

• Silver
• Gold
• Copper
• Bronze
• Tin
• Brass
• Magnesium
• Ferrous Metals (Iron and Steel)

The common corrosive gases and examples of how they are produced:

• Hydrogen sulfide (H2S) produced as effluent from pulp mills, oil refineries, heavy industrial and from decaying vegetation.
• Carbonyl sulfide (COS) produced from fossil fuel combustion (such as burning coal, gasoline or petrol, oil, etc.), wood fires and ocean surfaces.
• Sulfur Dioxide (SO2) produced from fossil fuel combustion and from smelting operations.
• Hydrogen chloride (HCI) produced from fossil fuel combustion and from ocean surfaces.
