  • Crumb rubber coating composition and method for protecting a surface
    Patent number: 9873816
    Abstract: A recycled crumb rubber coating with a hydrophobic surface and a method for making the same. The coating with a hydrophobic surface includes a recycled crumb rubber coating layer comprising about 24-50 wt % of a crumb rubber, and about 25-75 wt % of an epoxy comprising a liquid epoxy resin and an epoxy hardener, and a first silane film comprising at least one silane and disposed on a surface of the recycled crumb rubber coating layer to form the hydrophobic surface. The method includes (a) mixing a crumb rubber with a liquid epoxy resin to form a first mixture, (b) mixing the first mixture with an epoxy hardener to form a recycled crumb rubber coating layer, and (c) depositing a first silane film comprising at least one silane on a surface of the recycled crumb rubber coating layer to form the hydrophobic surface of the recycled crumb rubber coating.
