Using desiccant is an old, and frequent form of corrosion prevention for metal packaging, relying on reduced humidity to reduce corrosion. Desiccants, while effective in many applications, have been overtaken by Volatile Corrosion Inhibitors (VCI), which overcome some drawbacks of desiccants. VCI are less sensitive to damaged packaging and remain effective even after extended exposure to high humidity. VCI, however, does little to control the humidity inside of the packaging, leading some to want to combine the use of desiccant with VCI. In the following paper we will lay out issues with adsorbing VCI onto the desiccant, and damage to the desiccation ability as well as some of the improvements to longevity and moderation of emission that result when the two technologies are combined. The focus of the paper will be on deliquescent salts, superabsorbent polymers, clay, silica gel, and VCI emitting breathable pouches.
