  • Publication number: 20100325830
    Abstract: The present invention relates to a coating for elastomeric linear profiles, where the coating comprises solid lubricant embedded into a polymeric matrix. It also relates to a wiper blade for windscreen wipers, comprising this type of coating, and also to a process for the production of an elastomeric linear profile coated according to the invention. The polymeric matrix with embedded solid lubricant is obtained by polymerizing, in the absence of polymeric binders, a mixture comprising the solid lubricant and low-molecular-weight crosslinking agent. In one embodiment, the matrix is obtained from the thermal polymerization of the low-molecular-weight crosslinking agent hexamethoxymethylmelamine. Examples of solid lubricants are graphite and HDPE.

  • Patent number: 7384895
    Abstract: Thermally formed thermoplastic articles can be protected from stress cracking in the presence of stress cracking promoting compounds by forming a shaped article comprising a thermoplastic and a liquid hydrocarbon oil composition. We have found that the liquid hydrocarbon oil composition prevents the stress cracking promoting materials from interacting with the polymeric structure of the stressed container to prevent or inhibit stress cracking in such materials. The methods and compositions of the invention are particularly useful in preventing stress cracking in polyethylene terephthalate beverage containers during bottling operations during which the bottle is contacted with aqueous and non-aqueous materials such as cleaners and lubricants that can interact with the polyester to cause stress cracking particularly in the container base.

  • Patent number: 7166561
    Abstract: Paper shredders are maintained using lubrication substrates that have been treated with or that carry a lubricant. The lubrication substrate is fed through the shredding mechanism of a paper shredder. Rather than requiring disassembly of the paper shredder, maintenance and lubrication can be performed by passing the lubrication substrate through the shredding mechanism. The lubrication substrates can take any of a variety of forms, such as a tissue that is encased in a cellophane or plastic envelope and is impregnated with oil. The lubrication substrates can instead have an array of small tubes that carry oil. In another example, the lubrication substrates can take for them of a bubble sheet that carries oil within the bubbles.

  • Publication number: 20030130139
    Abstract: A waterborne composition for forming protective coatings to provide, by a simple method comprising coating and drying onto a metal surface, a coating that is uniform with little unevenness and that has an excellent galling resistance and workability that are at least as good as the corresponding properties afforded by conversion treatment methodologies, contains water-soluble inorganic salt and smectite-type clay mineral. The lubrication performance of the coating can also be improved when said composition additionally contains a lubricating component.

  • Publication number: 20020183209
    Abstract: A method for forming a solid film lubricant on the surface of a part having an arbitrary shape is provided. The method for forming a solid film lubricant includes: preparing a carrier having a predetermined shape and size; coating lubricant powder on the carrier; and coating the lubricant powder over the surface of the part by physical contact between the carrier coated with the lubricant powder and the part. The solid film lubricant has uniform thickness and excellent adhesion regardless of the shape of a target part. Lubrication of the solid film lubricant lasts for a longer period of time without supply of lubricant oil, and under high-load and high-speed operating conditions. Therefore, the solid film lubricant is applicable to a variety of parts widely used in aerospace, defense, and high-precision industries.
