Corrosion Intercept® is a revolutionary technological advance that bonds solid state reactive materials (bonded copper particles) into a polymer matrix. This matrix then reacts with and neutralizes all corrosive gases that pass through or come in contact with the film. Corrosion Intercept® provides effective tarnish protection for non-ferrous metals such as silver, gold, brass, copper, bronze, and ferrous metals (iron based). The inert material is non toxic, non-abrasive, temperature and humidity independent, and features a built in saturation indicator. When the copper color turns black, it is time to change the Intercept anti tarnish bag. It is successfully used by major jewelry manufacturers, NASA, The British Royal Mint and many other companies world wide.
