Terophon® Anti-Dröhn Compound

The sprayable Terophon® anti-drone compound is a solution for the effective structure-borne sound damping of thin-walled metal, plastic or aluminium sheets in industrial applications, transport engineering and mechanical engineering. As a dispersion-based material formulated from aqueous synthetic resin dispersions, mineral fillers and fibres, as well as integrated flame retardant additives, Terophon® offers a high-quality combination of vibration-absorbing properties, fire safety compliance and environmental compatibility: it is free from heavy metals, halogens and asbestos, as well as any substances hazardous to health or the environment.

In detail, the material works as follows: when sprayed or applied to the sheet metal structure, a uniform, adhesive-bonded layer is created, which reduces the natural frequencies of the substrate and significantly reduces the transmission of structure-borne noise into the surrounding component. Thin-walled sheets (traditionally critical in terms of resonance and vibrating surfaces) benefit particularly from this measure, as the mass and damping elements act specifically on the sources of vibration. Typical applications include sheet metal enclosures, machine casings, transport containers, vehicle bodies, building services casings and other metal structures where fire safety requirements also apply.

Terophon® is characterised by its ease of installation: the material can be easily sprayed or applied, even to complex geometries, pipes, cavities or hard-to-reach rear surfaces of sheet metal. This makes retrofitting or the acoustic optimisation of existing assemblies significantly easier and more cost-effective. The reduced installation time, combined with the effective results in terms of acoustic comfort and vibration reduction, makes the solution attractive to end customers as well as commercial users and manufacturers.

With Terophon®, we offer a high-quality anti-drone compound designed equally for B2C, B2B and industrial customers. It meets demanding technical requirements in terms of sound insulation, ageing stability and environmental compatibility, and helps to noticeably reduce operating noise, unwanted vibrations and sound levels.
