| 20090007990 | METHOD FOR PASSIVATING METALLIC SURFACES BY USING ITACONIC ACID HOMOPOLYMERS OR COPOLYMERS - A process for passivating a metallic surface by treating it with an acidic aqueous preparation comprising at least one itaconic acid homo- or copolymer. Passivating layers and metallic surfaces obtainable by means of the process. | 01-08-2009 |
| 20090250142 | Mg or Mg-Alloy Housing and Method for Producing the Same - A surface of a Mg or Mg-alloy housing of the present invention is subjected to wet blast using a mixture containing a chemical conversion treatment agent and an abrasive, whereby a chemical conversion film is formed on the surface of the Mg or Mg-alloy housing. Because of this, a chemical conversion film is formed simply on the surface of a molded product made of Mg or a Mg-alloy to reduce the correction by puttying, whereby a Mg or Mg-alloy housing is provided in which a decrease in yield and an increase in cost can be prevented. | 10-08-2009 |
| 20110114225 | CROSS LINKING THIN ORGANIC COATING RESINS TO SUBSTRATES THROUGH POLYFUNCTIONAL BRIDGING MOLECULES - Disclosed is a method for providing an anti-corrosion protective coating to a metal substrate that uses a coating composition comprising a resin and a polyfunctional bridging molecule to both bind to the resin and to chelate the bound polymeric resin directly to the metal substrate. One category of polyfunctional bridging molecules preferably includes at least one amine function to bind to a resin and at least one carboxylate, thiol, silane, phenolate, acetoacetonate, imine, phosphate, or phosphonate function to chelate to a metal substrate. It is theorized that the amine function can bind to certain pendent chains in coating resins through a Michael addition reaction while the carboxylate, thiol, silane, phenolate, acetoacetonate, imine, phosphate, or phosphonate functions chelate to the metal substrate. These polyfunctional bridging molecules provide an organic binding of the resin to the metal substrates. | 05-19-2011 |
| 20120175021 | Compositions Promoting the Accelerated Degradation of Metals and Composite Materials - A composition to decommission firearms is presented. The composition comprises a monomer, a quantity of calcium chloride; and sulfur-containing compound. The sulfur containing compound includes sodium persulfate and/or sodium thiosulfate. | 07-12-2012 |
| 20120205010 | CORROSION CONTROL METHOD OF METAL - The present invention provides a method of preventing a metal from corroding by giving a high corrosion resistance in the state of retaining the functions of the metal surface, a surface of a thin film material particularly. A stable silane coupling layer which has a robust bond is formed on a metal surface by using a silane coupling agent and an oxidizer in combination. | 08-16-2012 |
| 20130037175 | PREPARATION OF ITACONIC ACID HOMO- OR COPOLYMERS AND AMINE- OR AMIDE- CONTAINING ALCOHOLS FOR METAL SURFACE TREATMENT - The present invention relates to an aqueous preparation for passivating metallic surfaces, comprising itaconic acid homopolymers or copolymers and at least one amine- or amide-containing alcohol, to a method for passivating metallic surfaces by treating the surface with the preparation of the invention, to passivating layers and metallic surfaces obtainable by means of the method of the invention, and to the use of the preparation of the invention for passivating a metal surface. | 02-14-2013 |
