Maarten van der Wielen 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).

  • Thickening System and Method
    Publication number: 20090306254
    Abstract: Paint formulations that exhibit improved performance characteristics due to the presence of a combination of a cellulose ether (carboxymethylcellulose and/or hydroxyethylcellulose) and a network building polymer (gellan gum, carrageenan, etc., as examples) as a thickening system therein are provided. Such a combination permits long-term shelf stability of the paint formulation while simultaneously according effective flow, leveling, and other important properties to the final paint formulation. The combination of the cellulose ether and a network building polymer allows for a lower viscosity cellulosic compound to impart the desired rheological behavior therein while also permitting the other desirable characteristics noted above. Such paint compositions also exhibit improved atomization for spray applications with such a thickening system.
    Type: Application
