Our anti-drumming compounds are solvent-free and based on aqueous synthetic resin dispersions. They deaden sound, are flame-retardant and heat-insulating, adhere to many substrates and are easy to apply. The waterproof version remains permanently water-resistant.
There are five versions of the anti-drumming compound (Antiphon) with different physical properties, depending on the application.
Use and application
Field of application: The anti-drumming compound is used for the sound deadening of thin-walled sheet metal structures in plant and apparatus engineering, as well as in vehicle, railway wagon, ship and container construction. The product is also used for incineration plants, lifts, facade elements, ventilation ducts, power plant construction, etc. The hydrophobic anti-drumming compound is used wherever permanent water resistance is required in addition to the other properties.
Application: Ensure an even, continuous application. Use only clean tools.
Substrates: Steel sheet with anti-corrosion primer, galvanised steel sheet, anodised aluminium, coil-coated sheet, etc. The surfaces must be free from dirt, oil and grease. We generally recommend an adhesion test.
Coating thickness: 5 mm wet film thickness, corresponding to 4 to 4.8 mm dry film thickness, possible in a single pass.
Application equipment: Airless units with a ratio of 60:1 or more, air-assisted units of 12:1 (piston pumps) and screw conveyors with atomising air at an inlet pressure of approx. 3–4 bar. Manual application with a squeegee or spatula is also possible.
Application temperature: above 15 °C recommended.
Drying time: Dry for transport after 12 to 18 hours at 5 mm dry film and standard atmosphere 20/55. Forced drying up to 50 °C is possible.
