TEROSON Liquid Applied Sound Deadener (LASD)

TEROSON Liquid Applied
Sound Deadener (LASD)
Sound damping materials for a better environment
TEROSON LASD – Not something to
keep quiet about
A trend is taking hold across the automotive industry:
Sound-damping materials that can be sprayed
onto car bodies by robots are increasingly replacing
bitumen mats
Liquid applied sound deadener (LASD) significantly reduces the
structural born noise generated by the engine and the wheels
during the drive and it absorbs vibrational resonance. LASD is
applied directly to the car body to keep away unwanted noise from
entering the vehicle passenger cabin. LASD is a more effective
sound damping compared to traditional bitumen pads and melt
sheets.
TEROSON LASD is made of polymers, renewable and sustainable
raw materials and other active components to meet specific sounddamping requirements. Since OEM industry continues to pursue
acoustic comfort, light-weight, sustainability, process efficiency and
cost reduction, Henkel is providing the chemistry and the knowhow that makes this possible.
Benefits
>> Significant weight reduction compared to bitumen pads
>> Robotically-applied LASD assures consistent and reliable quality
>> Renewable and sustainable raw materials make LASD
independent from traditional materials
>> Succeeds current VOC limits for interior car body requirements
Applications
TEROSON LASD can be sprayed on car bodies by robot with
existing standard dispensing technology like flatstream.
Service and Support
Henkel supports its LASD customers before, during and after the
launch of the LASD technology. LASD can be easily implemented
into the existing manufacturing process.
