Sound damping compositions and methods for their application are described herein. The compositions can include a polymer, a polyacrylate rheology modifier, and a polyurethane rheology modifier. The compositions can alternatively include a polymer derived from greater than 80% of one or more monomers selected from the group consisting of butyl acrylate, 2-ethylhexyl acrylate, methyl methacrylate, methyl acrylate and ethyl acrylate and combinations thereof and greater than 0% and less than 4% of one or more functional monomers, at least one rheology modifier, and a surfactant. Also described herein are sound damping products including the compositions described herein and structures including the sound damping products. Methods for damping sound in a structure are further described herein. The methods include applying the compositions to the surface of a structure and drying the composition.

Sound damping compositions and methods for application and use

Styrene-butadiene-based aqueous dispersions and methods for their preparation are described herein. The aqueous dispersions include water and a binder comprising a styrene-butadiene-based copolymer and an epoxysilane. Further described herein are binder formulations and methods for their preparation and use.
