  • Patent number: 7160938
    Abstract: A lubricating/detaching/fluidifying additive composition for organic polymers is described, comprising a saturated hydrocarbon having from 25 to 35 carbon atoms with at least three side substituents consisting of a methyl group, combined with at least one polysiloxane polymer having a molecular weight higher than 500,000. The use of this composition or single hydrocarbon component as lubricating/detaching/fluidifying additive for organic polymers, is also described, together with a polymeric composition containing additives, comprising an organic polymer and the additive composition. The use according to the present invention is particularly advantageous as it is universal (the same additive for all organic polymers, regardless of their formulation); it allows the use of high viscosity/high M.W. polymers (suitable for extrusion), also in injection moulding, and enables the additive to be applied externally to the polymer.

  • Patent number: 7135512
    Abstract: A hydrido-silicone is incompletely reacted with (preferably) a long chain olefin under hydrosilylation conditions to produce a partially substituted hydrido-silicone that is further reacted under hydrosilylation conditions with a vinyl containing MQ resin to partially consume the remaining hydride species which is then reacted under hydrosilylation conditions to consume the remaining hydride species with a long chain olefin to produce a composition that is useful as an anti-mist agent in the coating of flexible supports.

  • Patent number: 7070713
    Abstract: A single component sag-free liquid ebonite composition having silane coupling agents selected to chemically bond and convert liquid unsaturated rubber to alkoxy functionality, to consume and scavenge moisture originally present in the mixture, and to react with sulfur during vulcanization. The single component liquid ebonite composition is moisture activated and is particularly useful for coating applications in protecting metal from corrosion and chemical attack. In some embodiments, the liquid ebonite composition having a total mass percentage of 100 is mainly composed of liquid unsaturated rubber, sulfur, a vulcanization activator, a vulcanization accelerator, a first silane, a second silane, and a third silane. With the right reactive functional group, the third silane can replace the first or second silane. In some embodiments, the liquid ebonite composition includes a catalyst, carbon black, fillers, additives, and a diluent or solvent.
