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.
