Kathleen H. Coventry-Saylor 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).

  • Method of preparing a stable, low pH phenolic resin
    Patent number: 6806343
    Abstract: A phenol-formaldehyde resole resin for use as a binder for glass fibers is acidified to a pH of 3 or less after base-catalyzed resinification. An increase in actual solids is observed compared with neutralized resin. Phenol-formaldehyde-urea-ammonia resins are surprisingly stable at pH 3 with desirable cure profiles.
    Type: Grant
    Filed: May 31, 2002
    Date of Patent: October 19, 2004
    Assignee: CertainTeed Corporation
    Inventor: Kathleen H. Coventry-Saylor
  • Method of preparing a higher solids phenolic resin
    Patent number: 6730770
    Abstract: A phenol-formaldehyde resole resin for use as a binder for glass fibers is acidified with sulfamic acid to a pH of 3 or less after base-catalyzed resinification. An increase in actual solids observed compared with neutralized resin, reflecting a desired improvement in efficiency.
