Decidamp SP500

water based vibration damping compound for premium applications

Decidamp® is a fast drying, water based viscoelastic vibration damping compound.

Optimised to suit transport and industrial applications, the advanced formula was developed for acoustic improvement of structures that are exposed to vibration and impact sound.

Decidamp damping compound is a lightweight, non-hazardous structural damping material that is suitable for exterior and interior use with easy application by simply spraying, rolling or trowelling onto surfaces. Once dry, the cured film is UV, water and chip resistant and exhibits low combustibility, it effectively absorbs and dissipates vibrational energy from the flexural stress of the base structure and reduces panel coincidence dip and resonance effects.

A superior extensional damping compound, it is suitable for applications to structures (fibreglass, aluminium, and steel, including stainless steel) where sound damping is required. Compliance to the latest international fire rail regulations, such as EN45545, makes it the ideal choice for premium transport applications.
