In admixture with the resin is a particulate vapor phase corrosion inhibitor selected from amine salts, ammonium benzoate, triazole derivatives, tall oil imidazolines, alkali metal molybdates, alkali dibasic acid salts, and mixtures thereof, and is present in an amount ranging from between about 1% and 3% by weight of the polymeric resin.

Abstract: A package containing a vapor phase corrosion inhibitor for use in forming film packaging envelopes. The package, and the method of forming the package include the selection of a suitable substrate board, and the application of a thermally activated adhesive film containing a quantity of vapor phase corrosion inhibitor onto the surface of the board. The films are thermal forming resins, such as a copolymer of ethylene and a vinyl monomer having an acid group thereon, and with the film resin also being blended with a vapor phase corrosion inhibitor. The vapor phase corrosion inhibitors used in the adhesive and in the film are selected from the group consisting of blends of alkali metal molybdates, alkali metal nitrites, triazoles, and amine salts. In forming the package, the films are initially heated or formed separately, and thereafter moved into contact with the substrate, this being undertaken with the peripheral areas of the film thereby becoming bonded to the substrate.

Abstract: Pulp prepared from post-consumer used or recycled paper may be employed in the preparation of substrates which are blended with a vapor phase corrosion inhibitor for preparation and fabrication of packaging enclosures or containers. The present invention permits substrates prepared in this fashion to be employed in such applications for which they are rendered highly suitable. Because of the unknown history of the post-consumer recycled materials forming the pulp, the utility of enclosures and/or packages prepared from such pulp is expanded. Vapor phase corrosion inhibitors useful in the present invention preferably include quantities of amine salts, alkali metal molybdates, including ammonium molybdates, or mixtures of molybdates with a second component such as benzotriazole.

Abstract: A resinous film at least partially formulated from a recycled resin and containing a vapor phase corrosion inhibitor. One embodiment of the invention is a single layer film which is formulated from three components. The first component is a recycled resin such as polyethylene, the second component is a fresh resin identical to the first, and the third component is a vapor phase anti-corrosion agent. Multi-layer films are also included. The films emit the anti-corrosion agent over a period of time to thereby protect items encased by the film.

Abstract: A package for facilitating the protection of metallic surfaces against corrosion and including a blend of corrosion inhibitor and surface-conditioning component such as a degreaser, descaler, and/or anti-static component in liquid state impregnated into a substrate such as a wipe for simultaneous and direct application to the surface of the article being protected. The corrosion inhibitor component is preferably an amine salt of carboxylic acid, triazole, an alkali metal salt of aldonic acid, or alkanolamine salts of fatty acids, an alkali metal or alkanolamine salt of aromatic sulfonic acid, or blends thereof. The substrate is preferably a wipe fabricated from a fabric such as soft cotton, but may also include other wipe materials such as woven or non-woven polyolefin fabric, or non-woven materials such as paper toweling.

Abstract: A vapor phase corrosion inhibitor-desiccant composite comprising silica gel granules coated with a vapor phase corrosion inhibitor component. The corrosion inhibitor component is selected from a formulation comprising anhydrous molybdates such as ammonium dimolybdate, sodium molybdate and amine molybdates mixed with benzotriazole and sodium nitrate, or from a formulation comprising amine benzoates, amine nitrates and benzotriazole. The composites can be impregnated into foam, extruded with polyolefin films which can additionally be laminated with metallized second film, or encapsulated in an air-permeable container. The corrosion inhibitor formulations have vapor pressures which provide ongoing corrosion protection for susceptible articles situated favorably with respect to the composite.

Abstract: A method of inhibiting corrosion of metal reinforcement structures embedded within cured concrete. The method comprises providing a plurality of exteriorly-accessible generally uniformly distributed openings in the concrete. Thereafter, a plurality of containers is provided, with each container having therein a migrating corrosion inhibitor and having a wall structure which is permeable to the migrating corrosion inhibitor. One container is placed in each of a sufficient number of openings in the concrete such that a sufficient quantity of migrating corrosion inhibitor exits from the respective containers and migrates through the concrete to the embedded metal reinforcement structures to thereby inhibit corrosion.

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.
