To pass NASA specifications a product has to go through rigorous testing with no outgassing or contamination. No volatile chemicals. Intercept changes color, providing an effectiveness indicator. Corrosion Intercept goes from Copper color to black, while Static Intercept goes from dark brown to black. There is still effective life left when the product goes black, however it is an indicator that new Intercept should be purchased.
Intercept is long lasting.
Intercept is effective for all types of metals, both Ferrous and Non-Ferrous. Intercept permanently reacts with and neutralizes corrosive gases. This is a chemical reaction that is not reversible. Intercept only works where it is needed. It specifically targets reactive gases only.
