The protective coating includes a non-tungstate anodic corrosion inhibitor and a cathodic corrosion inhibitor. | 01-01-2009 |
20090035473 | Conversion Coatings With Conductive Additives, Processes For Applying Same And Their Coated Articles - A coating composition includes a conductive polymer including at least one of the following: a single conductive polymer, a dual strand conductive polymer, a combination of a single conductive polymer and a dual strand conductive polymer or an organic-inorganic hybrid composite. | 02-05-2009 |
20090061184 | Processes for Applying a Conversion Coating with Conductive Additive(S) and the Resultant Coated Articles - A process for coating an article includes the steps of contacting an article with a first solution to produce a coated article, the first solution includes a solvent and at least one non-conductive material comprising at least one oxide of a metal; contacting with a second solution the coated article having at least one surface with a non-conductive material layer, the second solution includes a solvent and at least one conductive material comprising at least one of the foregoing: graphite, metals, conductive ceramics, semi-conductive ceramics, intermetallic compounds, and mixtures thereof; and drying the coated article having at least one surface with a non-conductive material layer having the at least one conductive material in contact with at least one surface of the non-conductive material layer and the at least one surface of the article. | 03-05-2009 |
20090117369 | Anodic-cathodic corrosion inhibitor-conductive polymer composite - A conductive polymer corrosion protective composite is provided which may be used as a coating for imparting corrosion protection to structures such as turbine engine components. The composite comprises an organic-inorganic component and corrosion inhibitive pigments comprising an anodic corrosion inhibitor and a cathodic corrosion inhibitor. The anodic corrosion inhibitor may be selected from the group consisting of compounds of vanadium, molybdenum, tungsten, and mixtures thereof. The cathodic corrosion inhibitor may be selected from the group consisting of cerium, neodymium, praseodymium, and mixtures thereof. | 05-07-2009 |
20110052462 | FILTERS FOR REMOVAL OF VOLATILE SILOXANES AND LIFETIME EXTENSION OF PHOTOCATALYTIC DEVICES - A filter for use in an ultraviolet photocatalytic oxidation air purification system having a filter surface treatment that enhances removal of volatile silicon-containing compounds (VSCCs). The surface treatment may create an acidic site on the filter, increase the surface area of the filter, or facilitate preferential interaction between the surface and the VSCCs, thereby promoting the VSCCs to bond with the VSCC filter. Removal of the VSCCs prior to the VSCCs reaching the photocatalyst increases the useful life of the photocatalyst. | 03-03-2011 |
