摘要： A mold-resistant gypsum panel includes a core of an interlocking matrix of calcium sulfate dihydrate crystals, a facing material on at least one side of the panel and a salt of pyrithione dispersed through both the core and the facing materials. A method of making a mold-resistant gypsum product is also provided. A slurry of calcined gypsum, water and a water-soluble pyrithione salt is formed, then deposited on a sheet of facing material. The slurry on the facing material is shaped into a panel and maintained under conditions sufficient for the calcined gypsum to react with the water to form a core comprising an interlocking matrix of set gypsum crystals. Heating of the panel causes evaporation of the water that did not react with the calcined gypsum.

摘要： A composition for a slurry for manufacture of acoustical panels includes one or more fillers, one or more binders, water and zinc pyrithione. At least of the fillers and/or binders includes microbial nutrients in an amount of at least 1% based on the dry weight of the acoustical panel. In another embodiment of the invention, acoustical panels include a core having a plurality of opposing surfaces and being at least ⅛ inches thick. The core comprises the dried product of a slurry of fillers, binders and water. Zinc pyrithione is present in at least one of the core and a coating applied to at least one of the surfaces of the core.
