  • Gypsum wallboard and method of making same
    Patent number: 9523198
    Abstract: A coalescing additive is used in the manufacturing process for gypsum wallboard. Such an additive increases the surface area and density of the slurry at the paper to core interface by coalescing the foam cells away from the paper core interface. This permits a stronger paper to core bond to form and increases the compressive strength of the gypsum wallboard as compared to standard wallboards made from slurries with reduced water levels.
    Type: Grant
    Filed: August 11, 2011
    Date of Patent: December 20, 2016
    Assignee: National Gypsum Properties, LLC
    Inventors: William C. Martin, Eli Stav, Matthew J. Plante, Maryn L. Heermann
