Description

Soundpaint is a water based damping compound of synthetic resin and fillers suitable for spraying or troweling onto surfaces to eliminate vibration noise. It works on a wide variety of materials, eg, metal, plastic and timber.

Application

Soundpaint is ideally suitable for applying in 1 mm thick coats to achieve the required thickness, requiring only 15 minutes drying time between applications. Soundpaint can be applied to areas such as car, truck or bus underbodies, boat hulls, enclosure panels, metal deck roofs, heavy earthmoving equipment and timber or metal floors.

• Hard wear resistant surface when dry.
• Eliminates ringing and tinning noise in metal structures.
• Environmentally friendly.
• Applicators can be washed out in water.
• Able to be painted over.
• Non-toxic
• Sprayable with airless spray gun.
• Ignition retardant.

Options

• Available with non-slip surface texture.
• Colours can be matched to customer specifications
• Viscosity can be adjusted to customer’s requirements.

Application Instruction

Areas to be covered must be thoroughly cleaned and dried before applying Soundpaint.

Manual Applicators

Hand mix the Soundpaint to ensure consistency. Smear the Compound onto the surface with a putty knife or similar tool. Working from the centre, apply thin coats of Soundpaint, multiple coats may be required to obtain the right thickness. For best results, apply a number of thin layers, allowing it to dry between coats.

Spray Applicators

When spraying Soundpaint, the compound must be stirred vigorously with a mechanical mixer to keep the paint thin.

1. Air spraying: The nozzle diameter should be minimum 4 mm and the pressure kept between 250 and 340 kPa.
2. Airless spraying: The nozzle diameter should be 1 mm and the pressure kept between 500 and 550 kPa.

Always keep the nozzle 250 mm to 400 mm from the surface when spraying the compound.

Guns should be immersed in water when not in use to prevent the compound drying on the spray gun. All lines containing the dampening compound should be cleaned with water after use.

Coverage

To obtain the best results, the finished wet layer (thickness) of the compound should be approximately 1 to 1½ times the metal thickness. One kilogram of Soundpaint will cover one square metre at a dried thickness of 1 mm. Depending on the humidity and ambient temperature, the drying time for 1 mm of Soundpaint can be as fast as 15 minutes.

Specifications

*Surface preparation: When using SoundPaint, ithe surface must be clean, dry and free of grease and oil.
