Patent number: 11884599Abstract: A slurry for manufacturing gypsum board is disclosed. The slurry comprises calcined gypsum, water, a foaming agent, and a thickening agent. The thickening agent of the present disclosure acts to improve the cohesiveness of the slurry without adversely affecting the setting time of the slurry, the paper-to-core bond (wet and dry), or the head of the slurry by acting as a defoaming agent or coalescing agent. Examples of suitable thickening agents include cellulose ether and co-polymers containing varying degrees of polyacrylamide and acrylic acid. A gypsum board and method of forming the slurry and the gypsum board are also disclosed. The gypsum board comprises a gypsum layer formed from the slurry.Type: GrantFiled: March 11, 2022Date of Patent: January 30, 2024Assignee: Gold Bond Building Products, LLCInventors: Eli Stav, Gopalakrisnan Sethuraman, Ma-Ikay Miatudila, Karen Fey, Joseph J. Bailey

Patent number: 10125049Abstract: A slurry for manufacturing gypsum board comprises calcined gypsum, water, a foaming agent, and a coalescing agent. The foaming agent imparts a plurality of bubbles in the slurry. Typically, a foam is pre-generated with the foaming agent and the foam is used to form the slurry such that the foam imparts the plurality of bubbles in the slurry. The coalescing agent coalesces the plurality of bubbles imparted by the foam. Typically, the coalescing agent coalesces a plurality of small and partially joined bubbles imparted by the foam to create larger and more discrete bubbles. A gypsum board and method of forming the slurry and the gypsum board are also disclosed. The gypsum board comprises a gypsum layer formed from the slurry. The gypsum layer defines a plurality of bubbles dispersed therein, which are imparted by the foam and coalescing agent of the slurry.Type: GrantFiled: September 24, 2015Date of Patent: November 13, 2018Assignees: BASF SE, NATIONAL GYPSUM PROPERTIESInventors: Ronald A. Lee, David T. Durocher, Sridhar Gopalkrishnan Iyer, Richard J. Romanek, Eli Stav, Karen Fey

Patent number: 9889579Abstract: Compositions for gypsum board are disclosed, comprising a mixture of a gypsum slurry and a pre-generated foam and a coalescing agent. The coalescing agent comprises one or more coalescing agents that are added to the composition singly, separately or in combination to change the size and distribution of the air bubbles in the foamed gypsum slurry. The resulting gypsum cores have increased nail pull resistance and an improved facer/gypsum core bond.Type: GrantFiled: September 3, 2014Date of Patent: February 13, 2018Assignee: National Gypsum Properties, LLCInventors: Eli Stav, Karen Fey, Gopalakrishnan Sethuraman, Ma-Ikay Miatudila, Craig Robertson, Joseph Bailey
