  • Patent number: 10072191
    Abstract: A de/anti-icer composition comprises one or more de/anti-icer moieties and a marker material, the marker material being selected such that, after application of the de/anti-icer composition to a traveled surface, the amount of the marker material at or on the traveled surface at a given time correlates to the amount of said one or more de/anti-icer moieties on the said surface at such time. The presence of the marker material enables the user readily to determine the concentration of the de/anti-icer moiety or the freezing point of liquid on the traveled surface. Methods of using such compositions for concentration and/or freezing point determination of de/anti-icer materials applied to traveled surfaces are described, together with systems and kits of parts utilizing such compositions.

  • Patent number: 8057642
    Abstract: This invention relates to a process for reducing the corrosion rate of iron-containing vessels within an ethylene glycol distillation system. The inventive process includes the addition of an additive component of sodium nitrite and sodium hypophosphite into such iron-containing vessels, to thereby react with iron of the inside walls and form a protective coating thereon. This process reduces the corrosion rate in iron-containing vessels of the apparatus, and reduces the catalytic effects of iron corrosion products within the system. Thus, not only is the on-stream time of the vessels extended, but also product quality is improved by reducing the aldehyde content of the final ethylene glycol product.

  • Patent number: 7744775
    Abstract: In one embodiment, a corrosion inhibiting composition is formed by combining: (a) an inorganic phosphate; (b) a water soluble polyelectrolyte polymer dispersant; (c) a tri or tetracarboxylic acid; and (d) at least one additional component comprising at least one of a C4-C22 aliphatic or aromatic mono- or dicarboxylic acid, a silicate and at least one of a silicone or a silicate stabilizing siloxane compound, and mixtures thereof. Also disclosed are heat transfer fluids that include about 5% to about 99% by weight of freezing point-depressing agent; about 1% to about 95% by weight of water; and the disclosed corrosion inhibitor composition. A method of reducing corrosion in a heat transfer system containing one or more components that contain magnesium or a magnesium alloy requires that the system and the magnesium containing components be in contact with the disclosed heat transfer fluid.

  • Patent number: 7513948
    Abstract: Systems and methods for enhanced autogenous healing of cracks that are formed or are present in concrete-containing materials and surfaces are disclosed. Treatment modalities that include addition of the disclosed materials, compositions and systems to pre- and post-construction concrete-containing materials and surfaces are provided. Autogenous healing is effected at a greater rate and to a larger degree as compared to control systems. The disclosed compositions and systems also yield reductions in the rate and/or impact of corrosion are achieved for concrete-containing structures and surfaces and, despite the water soluble properties of the compositions and systems, the treatments are effective in delivering an advantageous level of moisture resistance to the treated concrete-containing structure and/or surface. The composition is synthesized from a feedstock that includes C9 to C16 branched hydrocarbons of varying structures.

  • Patent number: 7498090
    Abstract: A combination includes a composition providing corrosion resistance for application to a post-construction material, and a post-construction material, wherein the composition is applied to at least one surface of the post-construction material after the post-construction material has hardened. The composition may include an effective amount of a thinning agent, e.g., isopropyl alcohol, ethanol, xylene or similar composition. The composition may be an aqueous solution of a metal salt of a dioic acid. The post-construction material may be reinforced or unreinforced concrete. The post-construction material may be a concrete-containing structure, and the composition may be applied to an exterior surface thereof.

  • Patent number: 7459102
    Abstract: A corrosion inhibitor that includes several oxo-anion compositions useful for preventing the propagation of pit corrosion on aluminum and aluminum alloys. The oxo-anion compositions may include soluble polymeric oxidic acids comprising combinations of molybdenum, phosphorous, tungsten, and silicon. These compositions are useful as corrosion inhibitors in high-moisture, corrosive environments, such as radiators and cooling systems. For low-moisture environments, these oxo-anion compositions can be reacted with a counter-ion, such as various metals, including, but not limited to the rear earth metals, to form a soluble salt. The salt can then be adsorbed onto a carrier, such as paint pigments, which can then be applied to the surfaces of aluminum and aluminum alloys. These surface adsorbates then become sparingly soluble and are gradually released over time in the presence of an aqueous corrosive agent so as to prevent propagation of pit corrosion.

  • Patent number: 7422793
    Abstract: Rinsing or sealing solutions comprising a rare earth element and a valence stabilizer for barrier films. The treated films contain a rare earth/valence stabilizer complex. The rare earth element is selected from cerium, praseodymium, terbium, or combinations thereof, and at least one rare earth element is in the tetravalent oxidation state. The rinsing or sealing solution may also contain an optional preparative or solubility control agent. The oxidized rare earth element is present in the coating in a “sparingly soluble” form. The valence stabilizers can be either inorganic or organic in nature. A number of rare earth/valence stabilizer combinations that match the performance of conventional hexavalent chromium systems are presented.
