Soundown’s DC-3 Damping Compound is a viscoelastic, sprayable liquid sound damper. It has been found to be highly effective in reducing vibrational resonance conditions in structures such as passenger rail cars, elevator cabs, marine passenger and cargo vessels, stainless steel sinks
and other plumbing fixtures, sheet metal panels, floor housings, and a multitude of other applications. DC-3 dissipates structure-borne vibrational energy and reduces radiated air-borne noise.
DC-3 is resistant to water and a variety of solvents, acids and corrosive gasses. It is non-toxic, non-flammable, almost odorless and exhibits exceptional aging characteristics.
Water based and non-toxic, DC-3 offers an efficient and effective alternative to solvent-based sprayable damping products, as well as sheet applied damping materials. DC-3 can be sprayed or toweled directly from the drum without thinning. After application, DC-3 cleans up with water.
A typical setup to spray. DC-3 consists of a 30:1 airless pump, a reverse-a-clean airless gun with a tip size of 0.043", a ram and a surge tank.
DC-3 exhibits exceptional adhesion to a variety of materials when properly applied, and air-dries within 24 hours at room temperature. The drying time can be accelerated through oven drying using moderate temperatures. Its normal "tan" color may be varied for decorative purposes.
