Patent abstract
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.
