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 materials react with and neutralize all corrosive gases that contact the film. It provides10 years of protection against corrosive gases 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)
  • 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.
