  • Patent number: 7645395
    Abstract: The present invention utilizes simple dimethylsilicone fluids of the proper viscosity/molecular weight added to modify the low temperature properties of polycyclic hydrocarbons. One preferred embodiment of a polycyclic hydrocarbon is a perhydro dimer of alpha-methyl styrene. Addition of the dimethylsilicone fluid to the perhydo dimer of alpha-methyl styrene improves the low temperature performance without degrading the requisite low shear stress shear strength properties. Low viscosity dimethylsilicone lubricating fluids combined with polycyclic hydrocarbons are suitable for use in infinitely variable transmissions providing good low temperature flow properties and high shear strength at high temperature and low contact stress conditions.

  • Publication number: 20040209784
    Abstract: A non-volatile lubricious coating composition is provided for use with medical devices, such as hypodermic needles, catheters, and the like. The coating composition includes a first siloxane polymer having a very low viscosity less than about 50 centistokes, a second siloxane polymer having a high viscosity greater than about 1,000 centistokes, a reactive silicone polymer which is capable of crosslinking upon exposure to radiation, such as a UV curable silicone acrylate, and a photoinitiator to accelerate cross-linking of the reactive silicone polymer. The coating composition may further include an aminofunctional siloxane polymer to promote adhesion to metal surfaces when used with needles. The coating composition provides flowability without the need for any volatile organic solvent, and is capable of curing to provide adhesion and lubricity.

  • Patent number: 6806240
    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 in 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: 6780823
    Abstract: A process for lubricating a container, such as a beverage container, or a conveyor for containers, by applying to the container or conveyor, a thin continuous, substantially non-dripping layer of a liquid lubricant. The process provides many advantages compared to the use of a conventional dilute aqueous lubricant.

  • Publication number: 20040147408
    Abstract: A lubricant for a run-flat tire system includes a water soluble, or water-miscible carrier, a thickener, and a surfactant. The thickener hereof retains its rheological properties and is not subject to permanent thinning shear. The base fluid is, preferably, a water-soluble polyhydroxyl or other polyhydric compound and the thickener is preferably a clay. When admixed with a surfactant and, optionally, a lubricity agent, the lubricant exhibits long term stability and (is resistant to heat buildup.) prevents the buildup of heat in the tire assembly when the tire is in the run flat condition.

  • Patent number: 6743758
    Abstract: The passage of a container along a conveyor is lubricated by applying to the container or conveyor a mixture of a water-miscible silicone material and a water-miscible lubricant. The mixture can be applied in relatively low amounts and with relatively low or no water content, to provide thin, substantially non-dripping lubricating films. In contrast to dilute aqueous lubricants, the lubricants of the invention provide drier lubrication of the conveyors and containers, a cleaner conveyor line and reduced lubricant usage, thereby reducing waste, cleanup and disposal problems.
