The doctor blade (1) works in combination with a cylinder (2) and consists of a steel support (3) with a polished surface coated with a layer of variable thickness of polymeric material, comprising: an ultrathin layer (0) which coats the whole surface of the doctor blade (1); a thicker layer (6) which coats one side of one edge (4, 5) of the doctor blade (1) or both sides of one edge (4, 5) of the doctor blade (1) or the same side of both edges (4, 5) of the doctor blade (1) or both sides of both edges (4, 5) or one side of the doctor blade (1) or both sides of the doctor blade (1). In any case, the thicker layer (6) coats at least the side of the edge (4 or 5) of the doctor blade (1) that works in contact with the surface of the cylinder (2) and the front head part of said side.Type: GrantFiled: July 11, 2006Date of Patent: December 15, 2009Assignee: C.B.G.

Publication number: 20090301712Abstract: Included within the scope of the invention is an article of cured fluoroelastomer composition bonded to an inert substrate. The cured fluoroelastomer composition includes a fluoropolymer, a silica, and an acrylate compound. The fluoroelastomer composition is bonded to the inert substrate with a bind having a bond durability of at least about 1500 pounds load at 20° C. The inert substrate may be a metal substrate or a ketone-based polymer substrate. Also included are methods of bonding a fluoroelastomer composition to an inert substrate that may be, for example, a metal substrate or a ketone-based polymer substrate. The methods include contacting a curable fluoroelastomer composition to an inert substrate and curing the fluoroelastomer composition to form a bond between the composition and the inert substrate. The curable fluoroelastomer composition of the methods includes an acrylate compound, a curing agent, silica, and a fluoropolymer that comprises at least one cure site monomer.Type: ApplicationFiled: March 27, 2009Publication date: December 10, 2009Applicant: Greene, Tweed of Delaware, Inc.Inventor: Ronald R.

Patent number: 7629023Abstract: A rust inhibitor which ensures the simplicity of application typical for a coating process and can demonstrate excellent characteristics similar to those obtained with a metal spraying method. The rust inhibitor is manufactured by admixing zinc and aluminum as fine powders of inorganic metals, which are manufactured with a stamping mill to have a flaky shape, to a modified silicone resin solution. A silane-type silicone resin is used for the modified silicone resin solution. For example, a mixed solution of an organosilane-type silicone resin and an oligomer-type silane coupling agent and the like is used.Type: GrantFiled: September 30, 2002Date of Patent: December 8, 2009Assignee: Primet Technology Inc.Inventors: Yuko Kurimoto, Kazuo Kobayashi

Patent number: 7629029Abstract: Compositions and methods of preparing functional thin films or surface coatings with low non-specific binding are described. The thin films contain specified functional groups and non-specific binding repellant components. The thin films are either covalently bound to or passively adsorbed to various solid substrates. The specified functional group provides specified activity for the thin film modified solid surfaces and non-specific binding repellant components significantly reduce the non-specific binding to the thin film modified solid surfaces. Non-specific binding repellant components do not affect specified functional group's activity in the thin films. In these methods, specified functional groups are anchored to the solid substrates through a spacer.Type: GrantFiled: October 13, 2004Date of Patent: December 8, 2009Assignee: Accelr8 Technology CorporationInventors: Guoqiang Mao, Steven W. Metzger, Michael J. Lochhead

Patent number: 7597935Abstract: A process for preparing a chrome substrate for application of a polymer coating, wherein the substrate preparation enhances adhesion and durability of the adhesion between the chrome substrate and the polymer coating, involves contacting the chrome substrate with an acid solution for a period of time sufficient to modify the surface of the chrome substrate. In certain embodiments, the acid treatment is an anodic treatment. In accordance with certain aspects of this invention, the acid treated chrome surface is further treated with a silane compound to enhance adhesion with a subsequently applied polymer coating composition.Type: GrantFiled: May 6, 2002Date of Patent: October 6, 2009Assignee: Lacks Enterprises, Inc.Inventors: Qihua Xu, Ling Hao, Lawrence P.

Patent number: 7592067Abstract: Disclosed are epoxy resin compositions which include an alkali metal containing cure accelerator. The alkali metal containing cure accelerators are preferably alkali metal hydroxides, alkoxides, carboxylates, or alkali metal salts. Articles prepared from the resin compositions of the invention exhibit enhanced thermal properties, and similar non-thermal properties, when compared to articles prepared from compositions including other accelerators such as imidazoles. The resin compositions of the invention may be used for any purpose, but are particularly suited to be utilized in the manufacture of laminates for printed circuit boards and non-electrical structural applications.Type: GrantFiled: September 22, 2003Date of Patent: September 22, 2009Assignee: Hexion Specialty Chemicals, Inc.Inventors: Walter H.
