NOXUDOL 3101

Noxudol 3101 is a waterborne viscous, elastic sound damping paste based on polymer, developed for users which have high demands on fire safety. Due to its viscous elastic flexibility it converts sound producing resonance into heat. The material holds good adhesive qualities and is water resistance when hardened.

Noxudol 3101 is a sound damping paste intended for metal and plastic in thickness between 0,5-5,0 mm, like car bodies, ships’ hulls, ventilating ducts etc. The material should preferably be applied with sprayer, but could be painted on or applied by roller. The product effectively eliminates disturbing sounds. The product contains anti corrosives and even gives some protection against condensation. Noxudol 3101 has a high damping factor despite low weight/unit area, approx. half the weight compared with traditional bitumen carpets. Noxudol 3101 has a high abrasion resistance.

Noxudol 3101 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 the material with a high-pressure pump (airless) 1:26>, sprayer or roller. It is 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 needle as large as possible.

To achieve an effective resonance and sound damping, apply a smooth layer of 1, 0-2, 5 mm dry film, the thickness 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 approx. 80%. This effect increases during the chemical hardening. Only after the film has hardened (7-14 days) Noxudol 3101 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.
