Silent Running soundproofing and vibration dampening products..
are the best performing and cost effective soundproofing and vibration dampening products. This liquid-based sound proofing coatings utilize a space-age viscoelastic polymer system that virtually eliminates unwanted sound and vibration problems. The viscoelastic properties of Silent Running liquid-based coatings absorbs the noise and vibration and converts it into low-grade heat, which is dissipated throughout the applied surface. It adheres to any surface and since it's a liquid, it goes on easy like paint with a brush, roller or spray, and takes up less space and weighs less than existing sound proofing technologies like mats and wraps. Just paint it on and feel the difference.
Silent Running is a nontoxic water-based vibration absorbing material. You apply it just like paint and it dries to a hard surface in a few hours. The viscoelastic properties of Silent Running liquid-based coatings make them the best performing, cost effective solution to your unwanted sound or vibration issue. The coating absorbs the noise and vibration and converts it into low-grade heat, which is then dissipated throughout the applied surface.
Why Should I use Silent Running?
Silent Running is a unique high technology liquid sound and vibration control product. It is basically a liquid sound-deadening agent. It literally removes noise and unwanted vibrations by converting them into low-grade heat. It does not have a foul smell and cleans up with soapy water. And it adheres to most surfaces.
Where do I use Silent Running?
Silent Running products are used all over the world to solve many noise and vibration problems in the Industrial, Transportation, Appliance, Marine, Construction and HVAC industries. Use it on boats, buses, RV's, airplanes, noisy machines and tracks, vibratory sorting devices, motor cabinets and more. Use Silent Running products anywhere there is a major source of noise, vibrations or motion.
works by converting noise energy and vibrations into a low-grade heat, which is then dissipated throughout the applied surface. It is a VOC compliant, water based product that is easily applied with a spray application. This sound damping paint can be used on the interior of the hull, stringers, engine beds, bulkheads, ceilings, hatches, engine boxes, bow thrusters, HVAC units, duct work, generator covers and mechanical enclosures. SR 1000 is designed as a “permanent” coating and has excellent adhesion to all metal, fiberglass, and wood. The key to Silent Running is to build it up, in multiple coats, to a minimum of 40mil final application thickness (depending on thickness of substrate).

SR 500 is designed as a “permanent” coating and has excellent adhesion to all metal, fiberglass, and wood. The key to Silent Running is to build it up, in multiple coats, to a minimum of 40mil final application thickness (depending on thickness of substrate).
is a high performance, viscoelastic coating used to dampen vibration and reduce unwanted noise. SR Car is easily applied to hot rods, cars, trucks or any vehicle with vibration and noise problems. Apply SR Car to wheel wells, rocker and door panels, trunk, firewall and all interior surfaces for a quiet ride.
Technical Info - How Silent Running Products Work
The easiest way to learn more about Silent Running products is to understand what makes sound. Sound is just a disturbance in the air. When the air vibrates your ears interpret it as sound. So basically, it takes something moving or vibrating to make a sound.
Take the stereo in your vehicle as an example. There are two things involved in your stereo, the radio or power source and the speaker. The power from the radio moves the speaker back and forth. If you want more volume you must add more power or turn up the volume knob. What do you think would happen if you added some weight to the speaker? It would not be as loud. That's because it takes more power to move the additional weight. How about if you could take weight away? The speaker would become even louder at the same place on the volume knob.
So you can make things louder or quieter by adding weight to the part that makes the sound, in this case the speaker. You could also do it by adding or subtracting power, in the case of your radio, watts. That's all the volume knob is doing, varying the amount of power the speaker gets.
The last thing to remember about sound is that it is logarithmic. There are some math principals behind it, but what it basically means is that if you add twice as much power, you do not get twice as much sound. When it comes to sound, adding twice as much power generally adds enough extra volume that you can just hear the difference. If you want to get twice as much volume, you must add 10 times the power! Just the opposite it true when you want to get rid of sound.
Driving along in you vehicle you basically encounter two types of noise, airborne and structure borne.
Airborne noise is coming from someplace outside your vehicle. Tire noise is the best example of airborne noise; a loud exhaust is another. This noise is generated outside of the vehicle and comes in through the windows. The easiest way to get rid of this noise is to roll up the windows. If that still doesn't work, then you may need to do other things like switch tire brands, get a quieter muffler, etc.
Silent Running is made to stop structure borne noises. These come from vehicle vibrations in the body panels, the engine, the suspension, the A/C system and more. With all these unwanted vibrations in check, the vehicle is much quieter on the freeway.
The old way of removing unwanted noise was to add heavy asphalt mats to the body metal. Believe it or not, this is still done today. What these heavy mats do is add mass to the body panel, often as much as the panel itself. This doesn't remove the vibration; it just lowers the intensity. Here's why: like in the speaker example above, the speaker keeps playing; it's just not as loud. That's because with the same power vibrating the panel, it can't move the extra weight as easily. The problem vibration is still there. Remember sound is logarithmic. So if you added twice the weight to the panel, it wouldn't remove half the sound, only enough that you could just hear it. You would have to add lots of asphalt mats to get rid of half the noise.
Silent Running WORKS IN A DIFFERENT WAY
Instead of being a Band-Aid and trying to cover up the sound, Silent Running works like a cure for the vibration problem. It actually gets rid of the vibration by converting it into low-grade heat.
What happens is the back and forth vibrations, or mechanical energy, are converted to thermal energy or heat. It would take a thermometer that could read down to .001 degrees to see it, but this ""Viscoelastic" conversion is what happens when you use Silent Running coatings.
Have you ever pushed on a rubber-like substance that didn't come back to its original shape as fast as you pushed it in? That's just what Silent Running is doing. It doesn't offer much resistance in one direction, but there's a lot in the other direction. The metal can move easily in one direction, but not the other, something like a speaker that could only move out and not back.
Silent Running does exactly what it says it does...
stops unwanted noise and vibration.
