    Abstract: 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.

    Abstract: Se describen composiciones para amortiguar el sonido y métodos para su aplicación. Las composiciones pueden incluir un polímero, un modificador de reología de poliacrilato, y un modificador de reología de poliuretano. Las composiciones pueden incluir alternativamente un polímero derivado de más del 80% de uno o más monómeros seleccionados del grupo que consiste de acrilato de butilo, acrilato de 2-etilhexilo, metacrilato de metilo, acrilato de metilo y acrilato de etilo y combinaciones de los mismos y mayor que 0% y menor que 4% de uno o más monómeros funcionales, al menos un modificador de reología, y un surfactante. También se describen aquí los productos que amortiguan el sonido que incluyen las composiciones descritas aquí y las estructuras que incluyen los productos para amortiguar el sonido. Los métodos para amortiguar el sonido en una estructura también se describen aquí. Los métodos incluyen aplicar las composiciones a la superficie de una estructura y secar la composición.
