Automotive Sound Dampening

BASF offers high-quality polymer dispersions that have been specifically developed for Liquid Applied Sound Damping (LASD) as well as a broad range of water-based adhesive raw materials that have been specifically developed for technical lamination.

Aqueous, liquid-applied sound dampings are increasingly used to optimize the interior acoustics of cars and railway carriages and to dampen the noise of household appliances. The systems have been designed to suppress the vibrations of the vehicle body or the casing and hence, to stop the humming sound. Due to their efficiency and their precise and automated application via spray robots, water-based LASD masses are the modern alternative to traditional bitumen mats. One significant advantage: Due to its efficiency, the aqueous technology leads to significant weight savings.

Liquid Applied Sound Damping (LASD)

Our contribution

As a pioneer in this field, BASF supports the technological change through innovative product developments: Our high-quality polymer dispersions that have been specifically developed for this application help our customers to formulate highly efficient aqueous sound damping masses. Moreover, our additives allow for masses to be rheologically modified to ensure an ideal spraying application
