Noxudol 3100 Product Information

Noxudol 3100

Waterborne sound damping paste


Noxudol 3100 is a waterborne viscous, elastic
sound damping paste based on polymers. Due to
its viscous elastic flexibility it converts sound
producing resonance into heat. The material
holds good adhesive qualities and is waterresistant
when hardened. The product contains
anti corrosives and also gives some protection
against condensation. Noxudol 3100 has a high
damping factor despite low weight/unit area
(approx. half the weight compared with traditional
bitumen carpets).

Range of application

Noxudol 3100 is a sound damping paste intended
for metal and plastic in thicknesses between 0,5-
5,0 mm, like car bodies, ships’ hulls, ventilating
ducts etc. The product effectively eliminates
disturbing sounds.

Instructions for use

Noxudol 3100 should only be applied on carefully
cleaned surfaces. Untreated surfaces of steel in moist
environment and amphoteric metal surfaces such as
unalloyed aluminium, zinc etc. which can react with
bases must be primed before treatment to ensure
good adhesion. Apply with a high-pressure pump
(airless) 1:26>, sprayer or roller. When using a highpressure
pump it is very important to switch off the
pressure when not spraying. Max. interruption with
pressure on, 1 minute. After switching off, the pressure
in the hose must also be let out by the pistol gun;
otherwise the material will pack in the hose and be
very difficult to remove. The pistol gun ought to be
front mounted, the hose reasonably wide and the
nozzle as large as possible.
To achieve an effective resonance and sound
damping, apply a smooth layer of 1,0 – 2,5 mm dry film,
depending on the basis. The film thickness will also
influence the drying time, normally 6-8 hours at room
temperature. At lower temperatures or high humidity
the drying time will increase considerably.
The product sets in two steps. First the water
evaporates, and then a chemical hardening takes
place during the next 7-14 days, depending on the
temperature. After the first step, the evaporation, the
film is dry, manageable and already has a sound
damping effect of around 80%. This effect increases
during the chemical hardening. Only after the film has
hardened (7-14 days) Noxudol 3100 is water and frost
resistant and can then also be top coated with most
paint. A practical test has to be done first on a smaller
area to make sure that the paste withstands the paint
