Patent ID: 7763213

Claim:
A method for inhibiting corrosion of corrosion-susceptible material, said method comprising: (a) providing a corrosion inhibitor package having: (i) a first enclosure barrier comprising one or more gas-impermeable materials and defining a first enclosed space; (ii) a second enclosure barrier comprising a gas-permeable, solid particle-impermeable material, said second enclosure barrier being disposed in said first enclosed space and defining a second enclosed space inside of said first enclosed space, said second enclosure barrier having mono-direction emissivity and permitting vapors to pass through said second enclosure barrier from within the second enclosed space; and (iii) a substrate having one or more volatile corrosion inhibitor materials disposed thereon, said substrate being disposed within said second enclosed space; (b) breaching said first enclosure barrier to thereby render said second enclosed space in gas communication with ambient environment external to said corrosion inhibitor package; and (c) placing said corrosion inhibitor package in proximity to corrosion-susceptible material.
