Abstract
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.
Claims32
A composition for a slurry for manufacture of an acoustical panel comprising one or more fillers, one or more binders, water and zinc pyrithione, wherein at least one of said fillers and binders comprise microbial nutrients in an amount of at least 1% based on the dry weight of the acoustical panel.
A mold-resistant acoustical panel comprising:
- a core having a plurality of opposed surfaces, said core comprising the dried product of a slurry comprising water, one or more fillers and one or more binders, said core having a thickness of at least ⅛ inch and wherein at least one of said fillers and binders comprises one or more microbial nutrients in an amount of at least 1% by weight of the acoustical panel;
- and,
- zinc pyrithione distributed through said core.
An acoustical panel comprising:
- a core having a plurality of opposed surfaces, said core comprising the dried product of a slurry comprising one or more fillers, one or more binders and water, said core being at least ⅛ of an inch thick and wherein at least one of said fillers and binders comprise microbial nutrients in an amount of at least 1% based on the dry weight of the acoustical panel;
- and
- a pyrithione salt having a solubility in water of less than 0.1% and being distributed through said core.
A mold-resistant acoustical panel comprising:
- a core having a plurality of opposed surfaces, said core comprising the dried product of a slurry comprising water, one or more fillers and one or more binders, said core having a thickness of at least ⅛ inch and wherein at least one of said fillers and binders comprises one or more microbial nutrients in an amount of at least 1% by weight of the acoustical panel;
- and,
- a coating comprising zinc pyrithione, wherein said coating is applied to at least one of said surfaces.
A coating composition to be applied to an acoustical panel, said panel comprising at least 1% microbiological nutrients, said composition comprising water, a film former and from about 0.01% to about 1% zinc pyrithione.
A mold-resistant acoustical panel comprising:
- a core having a plurality of opposed surfaces, said core comprising the dried product of a slurry comprising water, one or more fillers and one or more binders, said core having a thickness of at least ⅛ inch and wherein at least one of said fillers and binders comprises one or more microbial nutrients in an amount of at least 1% by weight of the acoustical panel;
- and,
- zinc pyrithione distributed through at least one of said core and a coating applied to at least one of said surfaces.
A method of making an acoustical panel comprising:
- mixing a slurry comprising one or more fillers, one or more binders, zinc pyrithione and water, at least one of said fillers and binders comprising microbial nutrients in the amount of at least 1% by weight of the dry product;
- forming a panel;
- and
- drying the panel.
