In the “Plating Clinic” that appeared in the October 2000 issue of Products Finishing, I commented on a problem regarding tarnishing/oxidation of copper deposits. A reader has suggested an excellent alternative to the use of silica gel as a desiccant. The suggested replacement is to use a “volatile corrosion inhibitor.” The parts are wrapped in paper or films that contain the volatile corrosion inhibitor. This material works by depositing a thin layer of corrosion inhibitor on the surface of the parts. Protection is afforded even in damp environments.
