摘要： A gypsum board comprises a cover sheet and a gypsum layer disposed on the cover sheet. The gypsum layer comprises the reaction product of an isocyanate, water, and stucco. The isocyanate increases the moisture resistance of the gypsum board. A method of manufacturing the gypsum board comprises the steps of combining the isocyanate, the water, and the stucco to form a slurry, and applying the slurry to a cover sheet to form the gypsum layer on the cover sheet.

摘要： Two-part aqueous coating compositions as well as methods of using thereof are described. The first coating component can comprise one or more polymers and the second coating component can comprise a flocculant. The first coating component and the second coating component can be provided as separate aqueous compositions. The first coating component and a second coating component that can be co-applied (e.g., simultaneously or sequentially) to a surface form a rapid set coating.
