Abstract: A gel-forming corrosion inhibiting composition may be employed to protect a metal article from corrosion. The gel-forming corrosion inhibitor composition is combined with water and delivered to an enclosed space at least partially defined by the metal article. Subsequent to delivery, the combination forms a gel to sustainably fill the enclosed space, thereby protecting the metal article from corrosion.

Abstract: A volatile corrosion inhibiting agent is provided for dispersion of a vapor phase corrosion inhibitor in a vapor stream that is passed into a sheath or other casing enclosing a metal bar, cable, or other tension member to protect said tension member from corrosion.

Abstract: A bio-based corrosion inhibitor composition includes a corn stillage product, and may be a substantially water insoluble fraction of corn stillage. The corrosion inhibitor composition is useful in protecting metal articles from corrosion.

Abstract: A volatile corrosion inhibitor may be in the form of, or derived from, molasses. Corrosion inhibition activity may be provided by molasses products, including molasses and/or any derivative product generated therefrom. Example molasses products include concentrated molasses, dehydrated molasses, molasses distillates or pot bottoms from distillation, extracted fractions of molasses, molasses fractions prepared by precipitation or membrane separation, and molasses residues remaining after removal of additional sugar or other targeted compounds. In one embodiment, the molasses-based corrosion inhibitor may be derived from sugar beet molasses.

Abstract: A corrosion inhibiting agent is provided as a finely ground powder that is dispensed into a sheath or other casing enclosing a metal bar, cable, or other tension member. The agents are produced by preparing salts of amines with benzoic acid or nitric acid, drying the salts, and grinding and screening the salts to provide a desired maximum particle size. Also disclosed is a dry fogging system through which the powder is applied to metal tension members enclosed in polymeric sheaths or other fluid tight casings.

Abstract: A corrosion inhibiting deicer composition includes an aqueous extract of corn stillage. The composition may be combined with a freezing point suppression agent to exhibit a freezing point of less than ?35° C. The composition may be applied as a deicer to corrosion-susceptible materials without substantial risk of corrosion.
