  • Publication number: 20110314706
    Abstract: An athletic shoe coating for traction enhancement includes a pressure sensitive adhesive (PSA) and a tackyfying resin and a film former initially in solution within a solvent suitable for application to the surface of a shoe sole in liquid form, such as by spraying, rolling and brushing the solution onto the shoe sole. After the solvent evaporates a film or coating attaches or is bonded to the shoe sole that exhibits the property of dynamically modifying the traction properties of the shoe sole when pressure and shear forces are applied to the coating. Such modification causes the exterior surface of the film or coating to “refresh” the exposed surface upon impact. This imparts continued tackiness over extended use. Impact modifiers may be added for controlled release of a solvent to temporarily dissolve or soften the film or coating to promote such refreshment of the coating outer surface.

  • Patent number: 7705056
    Abstract: A cannister-based, high solids, low and non-VOC aerosol adhesive and canister based system. The aerosol adhesive typically includes a high solids polymeric base, a hexane or cyclohexane and acetone solvent mixture and a compressed gas dissolved within the solvent. The compressed gas typically includes carbon dioxide, nitrogen, nitrous oxide and air. The aerosol adhesive is adapted to be filled into a cannister including a hose connected to the canister and a spray gun connected to the hose. The system typically includes high solids with a high viscosity. Thus the canister typically maintains high pressures up to 350 psi, but typically at 260 psi while maintaining 325 psi at 130° F., to deliver effective spray patterns.

  • Patent number: 7211611
    Abstract: Non-petroleum based oils replace traditional process oils used in rubber compositions in general and specifically in footwear applications. The replacement oils, derived from plant or animal sources, represent a renewable resource and provide other advantages. The oils contain a sufficient level and distribution of fatty acid side chains to partially incorporate into the rubber at low levels, and to act as internal plasticizers at higher levels. Other compositions are free of silane coupling agents and additives that generate carcinogenic nitrosamines.

  • Patent number: 6281272
    Abstract: A waterborne coating composition having a crosslinking agent and a dispersion of polymeric microparticles in an aqueous medium wherein the microparticles are prepared by first forming a mixture in the aqueous medium of ethylenically unsaturated monomers and a substantially hydrophobic, saturated fatty acid-containing polyester. The amount of fatty acid used to prepare the polyester ranges from about 20 to 80 weight percent of the total weight of the fatty acid-containing polyester. The fatty acid-containing polyester contains functional groups which are capable of reacting with the crosslinking agent. The mixture is particularized into microparticles by high stress techniques, followed by polymerization of polymerizable species within the microparticles to produce the polymeric microparticles. The amount of the fatty acid-containing polyester in the dispersion is at least 10 and up to 70 weight percent based on weight of the ethylenically unsaturated monomers and fatty acid-containing polyester.

  • Patent number: 5218056
    Abstract: A polyisoprene elastomer has a polyisoprene content with an average molecular weight in the range of 15,000 to 70,000 and preferably 25,000 to 50,000. This has been cross-linked with an unsaturated aromatic compound and cured with a sulfur or peroxide curing system. The elastomer has an extremely low compression set (0 to 5%) and an extremely low durometer (Shore A, 0 to 20). The elastomer is lightweight, soft, flexible and durable and its properties make its shock-absorbing and shock-attenuating characteristics unique. It is therefore highly suitable for insole and/or midsole components in footwear.
