Volatile Corrosion Inhibitors.

Significant reports covering the period since 1962 were selected for this study, with reference to relevant earlier works. Recent government RD on volatile corrosion inhibitors VCI has generally proceeded along three lines extension of tests defining the protective value of these materials for longer storage periods to steel equipment, tolerances of various nonferrous materials and finishes toward tarnishing or corrosion by these materials, and effectiveness of exterior packaging materials in extending use of these inhibitors to more severe exposures of water vapor and liquid. Volatile corrosion inhibitors in the form of salts, dissolved in oils, or coated on paper within enclosed shipment parcels or storage spaces offer improved corrosion protection to hare steel while it is in a ready condition for withdrawal and immediate use.
