Abstract

The present invention provides combined property, dual-action aqueous and dry compositions for application to a material, such as conventional Gypsum Wall Board, ceiling tiles, joint compounds, concrete and other interior building materials, prior to an exposure of the material to fire, or prior to, during or after exposure of the material to conditions favorable to the growth of microbes, and related methods. When compositions within the present invention are properly applied to a material prior to the material being exposed to fire, or prior to, during or after the material being exposed to conditions favorable to the growth of microbes, these compositions have the effect of reducing the amount of burning that occurs to the material, and/or reducing the amount or density of smoke and associated toxic gases produced by the material, when the material is exposed to fire. These compositions also have the effect of inhibiting or reducing the growth, build-up or deposit of microbes on the material when the material is exposed to conditions favorable to the growth of microbes.

Dependent claims

A dry composition for application to a material to reduce an amount of burning that may occur to the material, or an amount or density of smoke that may be produced by the material, or both, and to reduce, inhibit or prevent a growth of microbes on the material, comprising:

(a) at least one alkaline metal inorganic salt, wherein the alkaline metal inorganic salts are present in the composition in a combined amount that is effective for reducing or preventing one or more oxidation reactions that are required for a combustion of the material, for reducing or inhibiting a growth, build-up or deposit of microbes on a surface of the material when it is exposed to conditions favorable to the growth of microbes, or both;
(b) at least one potassium salt of an organic acid, wherein the potassium salts of an organic acid are present in the composition in a combined amount that is effective for enhancing a solubility of one or more components of the dry composition when present in an aqueous liquid, enhance one or more antimicrobial properties of the dry composition in comparison with dry compositions containing the same ingredients, and the same amounts thereof, but not containing a potassium salt of an organic acid, or both;
and
(c) at least one boron-containing compound, wherein the boron-containing compounds are present in the composition in a combined amount that is effective for reducing or inhibiting a growth, build-up or deposit of microbes on the material, to increase an ability of the material to reduce a spread of flame, or an amount or density of smoke or toxic gases produced when the material is exposed to fire, in comparison with compositions containing the same ingredients, and the same amounts thereof, but not containing a boron-containing compound, or both;
wherein the dry composition, when applied to the material in an effective amount, or at an effective application rate:
(i) reduces the amount of burning that occurs to the material, or the amount or density of smoke produced by the material, or both, when the material is subsequently exposed to fire;
and
(ii) when the composition is applied to a material prior to, during or after the material being exposed to conditions favorable to the growth of microbes, reduces, inhibits or prevents the growth of microbes on the material when the material is exposed to conditions favorable to the growth of microbes.

wherein the dry composition, when applied to the material in an effective amount, or at an effective application rate:
(i) reduces the amount of burning that occurs to the material, or the amount or density of smoke produced by the material, when the material is subsequently exposed to fire;
and
(ii) when the composition is applied to a material prior to, during or after the material being exposed to conditions favorable to the growth of microbes, reduces, inhibits or prevents the growth of microbes on the material when the material is exposed to conditions favorable to the growth of microbes.
