Silent Running SR-500 is a high performance coating specifically designed to eliminate unwanted sound and vibration. SR-500 works by converting noise energy and vibrations into a low-grade heat, which is then dissipated throughout the applied surface.

For automotive applications, SR-500 eliminates unwanted road and outside noise and vibration, offering manufacturers, drivers and passengers a quieter, more comfortable driving experience.
SR-500 liquid sound damping products are perfect for quieting down noisy machinery including motors, turbines, compressors, mounting brackets, sorting devices, chutes and hoppers, as well as, ductwork, bridges, tunnels and other OSHA applications.
SR-500 is lightweight, waterproof, resists chipping and corrosion and bonds permanently to your vehicle, making it the perfect solution for creating a quiet environment.
Tools Needed: Spray Gun, Roller or Brush
Materials Needed: None
The surface must be free from grease, dirt or rust. Lightly sand for better adhesion. The drying time at room temperature is approximately 30 minutes to 1 hour (depending on layer-thickness and relative humidity) but can be improved by the use of low heat and air movement. The curing process consists of two (2) steps. The water will dissipate during the first hour (product becomes dry to the touch), which will be followed by the final curing of the polymer. The second curing process takes approximately 24 to 48 hours. 2 coats are recommended.
