Decidamp SP150

water based vibration damping compound

Decidamp® SP150 is a fast drying, water based viscoelastic vibration damping compound and adhesive. Previously known as Soundpaint, this advanced formula was developed for acoustic improvement of structures that are exposed to vibration and impact. It effectively absorbs and dissipates vibrational energy from the flexural stress of the base structure and reduces panel coincidence and resonance effects.

Developed with a special polymer technology, Decidamp® SP150 is a lightweight, non-toxic structural damping material that is suitable for exterior and interior use and anywhere that noise can impact structure, comfort and function.
With exceptional fire properties and compliance with international fire codes it performs across marine industry, automotive and other applications.

Decidamp® SP150 is easy to apply by simply spraying, rolling or trowelling onto surfaces. Once dry, the cured film is UV, water and chip resistant and exhibits low combustibility.

Decidamp® SP150 is a superior extensional damping compound suitable to be applied directly to structures (steel, fibreglass and alloys) where sound damping is required. Available in grey as standard or other colours can be ordered.
Low-density properties and its exceptional performance-to weight ratio makes it the ideal choice for weight sensitive applications.

Installation

Decidamp® SP150 can be applied using the following methods:

Trowel: Simply apply and smooth as required.

Brush: For brush applications, we recommend adding 0.3% of water by weight per kg of product. This will assist in easier and smoother application. Use a wide 100mm thick nylon bristle brush. Keep brush well loaded with Decidamp® SP150 and use short strokes, applying a thick coat of approximately 2-3mm. Avoid “painting” back and forth as this will cause the coat to become too thin.

Roller: For roller applications, we recommend adding 1% of water by weight per kg of product. This will aid in an easier and smoother application. Using a short knap cloth roller, roll with short strokes, and try to avoid rolling back and forth, as this will cause the coat to become too thin. Use a light brush to “tip-off” the stipples if desired.

Air assisted and Airless spray systems: Four main spray systems are available for the application of Decidamp® SP150.
