TEROSON® Liquid Applied Sound Deadener (LASD)

TEROSON® Liquid Applied Sound Deadener (LASD)
Not Something to Keep Quiet About
The automotive industry is seeking more
sustainable and cost effective solutions. Liquid
Applied Sound Deadener (LASD) is one response
to these trends by providing mass reduction;
improved Noise-Vibration-Harshness (NVH)
performance; reduced operational complexity;
and compliance to expected environmental
regulation. LASD significantly reduces the
structural noise generated by the powertrain
and wheels during operation of the vehicle, by
absorbing and dissipating vibrational energy.
LASD is applied directly to the car body, keeping
unwanted noise and vibration from entering the
vehicle passenger cabin.
TEROSON® LASD is made of polymers, fillers and
other active components to meet specific sounddeadening and vibration damping requirements.
Since the OEM industry continues to pursue
quiet, lightweight, more fuel-efficient cars and
trucks, Henkel is providing the chemistry and the
know-how that makes this possible.
BENEFITS
• Robotically applied LASD assures consistent application, providing
reliable and sustainable NVH performance.
• LASD is a bulk NVH material which reduces inventory complexity and
logistics costs compared to conventional damping pads.
• LASD can be applied robotically utilizing existing MSA and Flatstream
dispensing technologies.
SERVICE AND SUPPORT
Henkel supports its LASD technology with experienced acoustic /
materials engineering, laboratory, and field service personnel. LASD
application systems can be easily added into existing body or paint shop
manufacturing processes.
Henkel’s Acoustic Engineering and Test Center provides customers with
performance analysis in acoustics for optimum NVH solutions. In addition
to panel vibration and sound propragation of a typical body structure,
they evaluate for vibration damping or stiffening body panels using
materials loss factor.*
*The ability of acoustic compounds to dampen vibrations can be assessed by measuring the flexural vibration according to ISO 6721. The acoustic performance loss factor is a
measure of the damping effect.
