  • Vapor phase corrosion inhibitor product and method containing a desiccant
    Patent number: 4973448
    Abstract: A product for inhibiting corrosion of corrodible items within closed containers which comprises a powdered solid composition capable of producing and releasing a vapor phase corrosion inhibiting compound. The powdered composition is enclosed within a sealed envelope which is formed of a sheet material impermeable to the powdered composition, but which is porous to the released vapor phase corrosion inhibiting compound released from the powdered composition. The vapor phase corrosion inhibiting compound produced and released by the powdered composition migrates through the sheet material and permeates the environment of a closed container of corrodible items.
