Teroson WT 112 DB is a secondary noise and vibration control mass for spray and spatula application, based on an aqueous synthetic resin dispersion with flame retardant additives.
Characteristics
- Environmentally friendly by the use of low toxicity raw materials (halogen, heavy metal and asbestos free)
- Demonstrates low flammability according to DIN 4102 Part 1, Class B 1 up to 4.5 mm dry film layer thickness
- In addition to high acoustic effectiveness the product also demonstrates thermal insulation properties
- Demonstrates reliable adhesion to stainless steel, galvanized steel sheets and anodized aluminium
- After complete drying, the material may also be painted
- Due to natural raw materials variances in colour among various batches may occur
Application
- Used for (sound deadening or absorption of structure-borne noise) secondary noise and vibration control on thin walled sheet metal constructions in the manufacture of vehicles, railway carriages, shipbuilding as well as plant and equipment building
- In addition, the product is also applied to ventilation ducts, fan housings, lifts, waste disposal units, to the rear side of facade elements as well as to container buildings
