Patents by Inventor Robert Richard Liversage

Robert Richard Liversage has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8333829
    Abstract: Sprayable liquid emulsion polymer coating compositions comprised of polymer resin and a plurality of additives for the purpose of protecting, restoring, reconditioning, rejuvenating, and enhancing the color, luster and durability of a multitude of different newer and older substrate types. These coating and sealing compositions are anti-mold, anti-graffiti, they withstand temperatures up to, and most likely in excess of, 300 degrees Fahrenheit without compromising their structural integrity, and they protect against the substrate-degrading effects of oxygen, ozone, UV-radiation, moisture and dry rot. They are also environmentally and user-friendly because they comprise minimal amounts of hazardous constituents.

  • Publication number: 20120082791
    Abstract: Waterborne, polymer based coating compositions for interior and exterior use on elastomeric substrates (such as tires) with one or more polymer latex resins (having one or more carboxylic acid groups) in an amount sufficient to provide polymer solids in an amount of from 5 to 50% by weight of the coating; optionally one or more coalescing agents in an amount effective to coalesce and fuse polymer particles of the polymer latex resin into a relatively stretchable film when cured; one or more defoaming agents in an amount effective to enhance foam dissipation prior to film formation; one or more coupling agents having a first reactive group which is capable of bonding with the one or more carboxylic acid groups and a second reactive group which is capable of bonding with an elastomers substrate. Also, a method for applying such compositions to elastomeric substrates, such as tires.
