Patents by Inventor Dennis Michael Sharpe

Dennis Michael Sharpe 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).

  • Two-component coating composition and method of preparation
    Patent number: 7396891
    Abstract: Aqueous coating compositions containing (1) a first polymer containing reactive functional groups with a selected level of carboxylic acid functionality and (2) a polyfunctional crosslinker agent containing functional groups that are reactive with appropriate functional groups of the first polymer, are disclosed. The two-component polymer compositions provide a combination of durability and ready removability of the final coating after curing. Two-component polymer compositions based on the first polymer containing hydroxyl functionality in addition to carboxylic acid functionality and use of a polyisocyanate as the polyfunctional crosslinker agent are especially useful as floor polish compositions.
    Type: Grant
    Filed: February 3, 2005
    Date of Patent: July 8, 2008
    Assignee: Rohm and Haas Company
    Inventors: Richard Thomas Gray, Alan Wayne Kohr, Dennis Michael Sharpe, Theodore Tysak
