Delta~db is a sound dampening, or sound damping, coating for structural and mechanical noise generated through substrates and surfaces.
Sound has two major ways of traveling - through substrates and via airborne movement. To decrease sound prior to airborne transmission, it is very important to "kill" or dampen the noise vibration prior to its release to the airborne state. Delta~dB has special materials which are encapsulated in a high grade acrylic based binder that provides damping across the various frequency ranges. In fact, Delta~dB was tailored to control this transmission, turning the energy into low grade heat. This translation offers an efficient means to damping or "killing" sound through the substrate or surface. For more information on sound translation please see Sound Transmission, an informative essay about the nature of sound.
Delta~dB offers a very cost effective solution to sound damping problems in a flexible, monolithic coating format. Our unique chemistry and well-proven Dispersion 2™ technology gives the best sound damping abilities in an easily applied spray, brush or roll format. Delta~dB Sound Damping Coating can also be applied quickly without cutting or taping bulky type materials or having to glue and pin to surfaces. Its direct adhesion to the surface with its high grade resin system provides a "no worry" attachment for years to come. |

| Marine Applications |
Delta~dB Sound Dampening can be applied direct to aluminum, stainless, brass, fiberglass, etc without the need for a primer. It can be applied via airless, conventional, brush, roller or SA Gun setup with ease. This coating is specially designed to be applied to a thickness of 40 mils (1.0 mm) in a single applications. Typically, applying two coats to the substrate provides the most cost effective sound damping characteristics, however more coats may be applied without any upper limitations. Delta~dB Sound Damping Coating is a no VOC product and completely solvent free, as it is water based. Cleanup is simple with soap and water. |
| Transportation Applications |
Delta~dB Sound Damping Coating is an excellent lightweight material that can be applied to most any other surface to dramatically reduce road structural noise. This coating can be applied to the interior or exterior of a vehicle with ease damping the noise before it is released into the car, truck, bus, etc. Since it remains flexible when the coating dries, it will remain attached to the surface without any risk of de-bonding for years to come. |
| Other Applications |
Delta~dB Sound Damping Coating can also be used on industrial and other equipment that produce high levels of noise due to structural translation. The coating can be applied directly to most surface to effectively lower noise prior to airborne release. Where noise level safety is concerned, Delta~dB offers a very cost effective solution with minimal effort. Another added benefit is that the surface or equipment always remains viewable so that inspectability never becomes an issue like it would be with conventional tile and bulky sound insulation. |
| Sound Testing |
Delta~dB Sound Damping Coating was tested to show the performance of the coating on a surface vs a non coated surface. The test was performed on simple school bells. Since a school bell generates a lot of sound transfer from a little source, the result of a coated bell would show the differential easily. Both bells were setup in a test that exposed 10 lbs of force to ring the bell on a weighted arm. The microphone was attached in an identical place 1.5" from the bell source. The non coated bell weighed 105 grams and the coated version weighed 120 grams. Temperature for the test was 72 Deg F. Delta~dB was applied with a Small Application sprayer in two coats with approximately 4 hours dry time in between coats. The coating was allowed to cure for 7 days.
The following graphs show the non coated version of the bell vs. the coated bell. The relationship of the graph is decibels (dB) on the "Y" axes - vertical area) and time of the vibration or sound on the "X" axes (horizontal area).

| Application of Delta~dB |
The coating can be applied with an Airless, conventional, brush roller or SA Gun. Prior to application on carbon steel, there will need to be some sort of primer, as the coating is water-based. For aluminum, stainless, brass, fiberglass, etc, Delta~dB Sound Damping Coating can be applied directly. Although this coating has a paint-like consistency, it is one of the few sound damping coatings that can support its weight on vertical and overhead surfaces to 40 mils (1.0mm) wet! This is important as the coating can be applied quickly without the risk of sagging or sliding. Another great aspect is its rapid dry time. Delta~dB will dry to touch within one hour of application in temperatures above 70° F. Usually the coating can be recoated at this time so that the end application is done within your specified time frame. |
