Beschreibung
Zusammenfassung:	A thin drywall board that includes a gel coat, at least one polymer/gypsum layer, and a wet glass fiber layer is provided. The gel coat is formed of a gel coat composition that includes a water dispersible polymer, gypsum, and optionally a crosslinking agent and/or a coupling agent. The polymer/gypsum layer is formed of a matrix composition that includes a water dispersible polymeric resin and gypsum. Components including melamine formaldehyde, a filler material, coupling agents, acetic acid, an accelerator, and/or a hardener may also be added to the matrix composition. The wet glass fiber layer is preferably a glass fiber mat. The combination of the water dispersible polymeric resin and the gypsum in the matrix composition have a synergistic effect that creates a thin drywall board that is water resistant, fire resistant, and has improved mechanical properties. A method of forming the inventive thin drywall boards is also provided.
