Abstract
Described herein is a fire-resistant adhesive coating composition which emits water vapor when exposed to fire. Such compositions comprise an ionic polyacrylate dispersant, aluminum hydroxide, silicate, and an alkoxylated alcohol. In certain embodiments, the composition comprises a solids content of at least about 44.2%, based on the wet weight of the composition. Also described herein are methods for making and using of such coating compositions.
Claims18
A fire-resistant adhesive coating composition comprising:
- an ionic polyacrylate dispersant;
- aluminum hydroxide present from about 20.0% to about 35.0%, based on the total dry weight of the composition;
- potassium silicate present from about 65.0% to about 85.0%, based on the total dry weight of the composition;
- and
- alkoxylated alcohol.
A method for producing a building panel comprising a fire-resistant adhesive coating composition, the fire-resistant adhesive coating composition comprising:
- an aqueous liquid solvent;
- an ionic polyacrylate dispersant;
- aluminum hydroxide present from about 20.0% to about 35.0% based on the total dry weight of the composition;
- potassium silicate present from about 65.0% to about 85.0%, based on the total dry weight of the composition;
- and
- alkoxylated alcohol,
- the method comprising:
- i) coating a building panel with the fire-resistant adhesive coating composition;
- and
- ii) drying the fire-resistant adhesive coating composition to evaporate the aqueous liquid solvent;
- wherein the coating composition has a solids content of at least about 44.0%, based on the wet weight of the composition.
