Developed by Lucent Bell Labs to solve problems they were experiencing with 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 Non-Ferrous metal (such as Silver, Tin, Copper, Brass, etc.) corrosion.
The common corrosive gases and examples of how they are produced:
Key Benefits Intercept protects against Corrosion Damage:· Hydrogen sulfide (H2S) produced as affluent from pulp mills, oil refineries, heavy industry 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 (HCl) produced from fossil fuel combustion and from ocean surfaces.
Ø Reacts with and permanently neutralizes corrosive gases
Ø Provides corrosion protection for 10 years per mil of Intercept material
Ø Effective against Galvanic coupling (corrosion between joined dissimilar metals)
Ø Leaves no detectable deposit on any product it protects (unlike VCI's)
Ø Cleanses trapped air of corrosive gases
Ø Provides cost savings by eliminating secondary packaging and cleaning operations
cleaning operations often required with VCI protection or no protection
Ø Acts as a passive Bactericide and Mildewcide
Ø Eliminates the need for storage in inert atmospheres
Ø Environmentally friendly with substantially reduced landfill time (breaking down
into Polymer dust) and fully recyclable (meeting tough German recycling laws)
Ø Effective corrosion protection for the following materials:
z Silver z Copper z Bronze z Tin
z Brass z Magnesium z Ferrous Metals (Iron and Steel)
z Galvanic couples (if the Intercept is in intimate contact)
