Megasorber A200 is a high-tack and high-temperature resistant adhesive utilising the latest polymer-alloy technology. It allows the re-positioning of acoustic panels.

Odourless and fast curing

Megasorber A200 is a high-tack and high-temperature resistant adhesive utilising the latest polymer-alloy technology. It is a one-component moisture-cured adhesive.

Megasorber A200 adhesive is free of solvent, isocyanate, PVC and silicones. It is natural, odourless and fast curing.

Megasorber A200 adhesive has a temperature resistance up to 200°C (short-term exposed for 10 minutes) once cured. It forms an extremely strong bond once fully cured, and a mechanical method has to be used to remove it.

This adhesive has very good UV resistance, aging resistance and chemical resistance.  It is suitable for harsh environments, such as swimming pools, mining and outdoor applications.

Available in cartridges or sausages.

  3. Product code with optional extra:
  4. G8 facing may have a stripy appearance and creases. Hairline creases may appear on the facing when The creases do not affect the acoustic performance.
  5. There are colour variations between batches; whilst we take every care to minimise batch-to-batch variation, in some instances, variation may be unavoidable and will occur.
  6. Dimensional change will occur in the FM foam substrate with a change in relative humidity and temperature, this may cause creasing on the Soundmesh® G8 facing. The creases do not affect acoustic performance.
  7. Thickness tolerance is ± 5% and sheet dimension tolerance is ± 1%.
