Decidamp SP150 pail 20Kg

Item 1 of 1

Decidamp® Soundpaint is a fast drying, water based viscoelastic vibration damping compound. Optimised to suit marine and offshore applications, the advanced formula was developed for acoustic improvement of structures that are exposed to vibration and heavy impact.

Decidamp® SP150 damping compound is a fast drying, water based viscoelastic vibration damping compound. Previously known as Soundpaint, this advanced formula effectively absorbs and dissipates vibrational energy from the flexural stress of the base structures (steel, fibreglass and alloys) and reduces panel coincidence and resonance effects. Decidamp® SP150 is a lightweight, non-toxic structural damping material that is suitable for exterior and interior use. With exceptional fire properties and compliance to international fire codes it performs extremely well in Marine applications. Simply spray, roll or trowel onto surfaces requiring damping. Once dry, the cured film is UV, water and chip resistant and exhibits low combustibility.  Decidamp SP150 Soundpaint complies to latest international marine fire standards MED and is IMO/SOLAS certified.

A superior extensional damping compound with low-density properties it is the ideal choice for weight sensitive applications.
