Abstract: A corrosion inhibited formulation for drilling compositions consisting essentially of an environmentally friendly corrosion inhibitor blended with an alkali metal formate. The corrosion inhibitor is prepared pursuant to a process including the steps of: (1) preparing a reactant mixture comprising a fatty acid such as soya fatty acid or tall oil fatty acid with polyfunctional amines; (2) subjecting the reactant mixture to a temperature of between about 130 and 170 for a period sufficient to substantially complete the reaction to obtain a fatty acid amido amine product; (3) solubilizing the reactant product with an organic acid such as acetic to produce a product that is substantially completely soluble in aqueous solutions; and (4) blending the water soluble inhibitor salts into the buffered formate media.

Abstract: The method of adding migrating corrosion inhibitors to a raw concrete mix by loading a migrating corrosion inhibitor in powder form within a container fabricated from a water soluble film, and thereafter depositing the container into a hydrated concrete mix for blending. The container is preferably fabricated from a film consisting of polyvinyl alcohol.

Abstract: An improved method and/or process for preparing and handling formulations useful in metal treatment baths which includes packaging formulations useful in preparing and/or replenishing aqueous-based baths in water soluble pouches or containers. The present invention includes the selection of components effective in treating metallic surfaces, which may be blended and effectively stored in containers or pouches consisting of polyvinylalcohol film. The present invention reduces the necessity or frequency of personal hand contact by workers with these blends.

Abstract: A concrete sealer material is provided containing a corrosion inhibitor which is free to migrate upon leeching from the concrete sealer. The inhibitor retards the rate of corrosion of reinforcements contained within the concrete, including metallic mesh, grid, rebar, and other metallic articles utilized for reinforcement. The sealer material is preferably a film forming component of silicate or silane modified siloxanes. The corrosion inhibitor is preferably an amine salt, an amino alcohol, alkalized salt of glucoheptonates, or, calcium nitrite and mixtures thereof. A compatibility enhancer of an aminoalkyl silane can be added to the blend.

Abstract: A method of protecting water reservoirs or enclosures utilized in thermal energy conversion applications against corrosion during periods of shutdown by depositing a source of a vapor phase corrosion inhibitor, preferably a blend of ammonium benzoate, sodium benzoate, sodium sebacate, monoethanolammonium benzoate, benzotriazole, and cyclohexylammonium benzoate within the enclosure through the steps of packaging a vapor phase corrosion inhibitor in powder form within a container fabricated from a water-soluble film; perforating the walls of the container; depositing the perforated container within the enclosure being protected; and introducing water into the enclosure at the end of the shutdown period for simultaneously flushing the enclosure and removal of both the residual corrosion inhibitor and water-soluble container therefrom.

Abstract: Corrosion inhibiting thermoplastic alloys and methods of preparing same for use in fabricating molded articles with long-term corrosion protection. Masterbatches of an ABS resin together with selected corrosion inhibitor formulations are extruded for use in molding operations particularly adapted for preparing protective enclosures for delicate metals, such as are present in electronic media devices and apparatus. Molded articles are prepared from acrylonitrile butadiene styrene resin and a solid phase corrosion inhibitor blended in situ, and wherein the resin consists essentially of acrylonitrile butadiene styrene, and wherein the corrosion inhibitor contains a blend of dicyclohexylammonium nitrite, sodium nitrite, benzotriazole, sodium molybdate and sodium sebacate.

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.
