Soundproof Coating Designed to Eliminate Unwanted Noise

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

Offered in a conveniently sized gallon tub, you’ll have enough coating to fulfill a smaller-sized project. Our Silent Running coating is also easy to reorder without making a bulkier purchase. Oftentimes, one gallon will suffice for touch-ups. Our Silent Running SR-500 1 gallon supplies enough liquid to cover roughly 40 square feet. Simply use a brush or paint roller for a simple, smooth application of this soundproof paint.

If you’re looking to prevent noise disturbances and vibration, you want to do it right. Our Silent Running SR-500 soundproof coating won’t chip or crack, even when the surface expands, bends or flexes — that’s quality assurance. It’s simple to apply our Silent Running SR-500 coating, too. You won’t have to suffer harsh smells, spills are easy to clean up with soap and water and application occurs faster than other traditional methods.  The SR-500 is a great solution for Automotive, Boats, HVAC or almost anywhere vibration control is needed.

  • General Properties: SR-500 is water-based, non-toxic and VOC-compliant. There are no harsh smells. Before curing, it can be cleaned up with water.
  • Adhesion: SR-500 is designed as a “permanent” coating. The product has excellent adhesion to all metal, fiberglass, wood and most plastic surfaces. Proprietary components are added as “adhesion promoters” to help ensure it’s permanent adhesion. Adhesion is not affected by harsh cold or extreme heat. SR 500 can withstand temperatures from -30F up to 250F.
  • Durability: Although SR-500 dries to a hard surface, it retains excellent elongation. SR-500 will not chip or crack with any expanding, flexing or bending of the substrate. SR-500 cures virtually waterproof and is resistant to gas, oil and most chemicals.
  • Flammability: SR-500 is non-flammable. Should the product come into contact with flame, it is self-extinguishing.
  • Safety: Because of its water-based formula, SR-500 meets or exceeds all environmental standards.
  • Application: SR-500 applies faster and more easily and penetrates where other traditional methods of damping cannot.
  • Clean Up: Spills and mistakes are easily taken care of with soap and water.

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.

The times I talked with you on the telephone and corresponded through email you have been very helpful and efficient. I would highly recommend to anyone!

– S. Cimino, PA

I have emailed a lot of different manufactures and I have to say your customer service is head and shoulders above all of them. I emailed your company at about 9pm my time and when I woke up the next morning you had already answered my question and then the follow up was a few hours later. I am impressed. Thanks a lot for the quick turn around!

– E. Gustafson, NV

I just wanted to send a quick thank you for your rapid response and helpfulness. I very much appreciated it. You have been responsive in every way all through the process. It has been a pleasure doing business with you and your company.

– T. Alexander, CA

I just wanted to let you know that in the end, sealing the air spaces on this door worked just fine and took care of the problem.

I really appreciate you taking so much time to share your expertise with me, and in particular recommending I try the simpler solution before investing in more expensive noise barriers. That is a big credit to you and your business.
