20080251205 | Method for Preparing a Membrane Electrode of a Fuel Cell - The invention provides a method for preparing a membrane electrode of a fuel cell, comprising the steps of preparing diffusion layers, and superimposing the diffusion layers on a proton exchange membrane having a catalyst layer on each surface, wherein the method for preparing the proton exchange membrane having a catalyst layer on each surface comprises the steps of: filling a catalyst slurry containing a catalyst and a bonding agent between two polymer films, and pressing the polymer films filled with the catalyst slurry to obtain a catalyst layer; and superimposing the catalyst layer on each surface of a proton exchange membrane. The method of the present invention can control the thickness of the catalyst layers by pressing during preparation thereof, therefore, the catalyst layers have an even thickness and surface. | 10-16-2008 |
20080295961 | ACCELERATED ORGANOBORANE INITIATED POLYMERIZABLE COMPOSITIONS - The invention is a two part polymerizable composition comprising in one part an organoboron compound capable of forming free radical generating species and in the second part one or more compounds capable of free radical polymerization and from about 20 to about 30 parts by weight based on the weight of the second part of i) a halogenated polyolefin having halosulfonyl groups or ii) a mixture of a halogenated polyolefin and an organic sulfonyl halide. The second part may further contain a compound capable of causing the organoboron compound to form free radical generating species upon contacting the two parts. The first part may further comprise one or more compounds capable of free radical polymerization. | 12-04-2008 |
20090114343 | Hot melt adhesive for PTFE - Hot melt adhesives include a thermoplastic terpolymer of vinylidene fluoride, tetrafluoro ethylene and hexafluoropropylene and a terpolymer of glycidyl methacrylate, ethylene and an acrylic ester. The adhesives will bond well to a variety of substrates, in particular substrates of very low surface energy such as polytetrafluoroethylene (PTFE). | 05-07-2009 |

20140020828 | Fast Curing CPVC Solvent Cement - A composition and method of using the composition are described. The composition is useful for quickly bonding chlorinated polyvinylchloride during installation and repair operations. Embodiments of the composition include at least one volatile organic solvent, chlorinated polyvinylchloride dissolved in the solvent and the composition is substantially free of cyclohexanone. | 01-23-2014 |
20140305588 | Method of Bonding Perfluoroelastomeric Materials to a Surface - The invention includes a method of bonding a perfluoroelastomer material to first surface that includes: (a) contacting a first surface with a bonding agent comprising a curable perfluoropolymer and a curing agent; (b) curing the bonding agent to form a perfluoroelastomer material that is bonded to the first surface. In the practice of such method, the bonding agent may be a solution prepared by dissolving the curable perfluoroelastomer and the curing agent in a solvent. In an embodiment of the invention, the perfluoroelastomer material formed in step (b) is a coating layer or, alternatively, the first surface is a surface of a perfluoroelastomer member and the perfluoroelastomer material formed is a perfluoroelastomer weld. | 10-16-2014 |
