Vibration is the primary source of annoying sounds; Noxudol 3100 offers an effective and time saving way of preventing structure-borne sounds. The compound has a documented high damping factor and approximately half the weight compared with traditional sandwich metal plates.
Besides having a low weight, the compound is simple to apply by means of spray equipment or brush. One spraying can achieve 2 mm dry film thickness. Working time can be reduced by up to 80 % by using Noxudol instead of traditional sound damping material. The material is intended for metal and plastic in thickness between 0,5-5,0 mm. The properties of Noxudol 3100 are highly appreciated by shipyards, train manufactures, the vehicle industry and other sectors.

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 high-pressure 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 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, 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.
