Abstract
This invention provides aqueous flame retardant dispersions comprising water, a brominated flame retardant containing aromatically-bound bromine, at least one dispersant, at least one wetting agent, and at least one thickener. The brominated flame retardant has an average particle size of about 20 μm or less. The flame retardant dispersion contains about 50 wt % or more of brominated polymeric flame retardant, based on the total weight of the dispersion. Also provided are coating compositions, processes for forming flame retardant dispersions, processes for forming coating compositions, and processes for applying the coating compositions to textile substrates.
