Noise Reduction for the Automotive Industry

NVH, or Noise, Vibration and Harshness, is the study, testing and modification of the noise and vibration characteristics of vehicles in the automotive industry. With more efficient and quieter engines, virtually noiseless electric motors, and the goal to reduce vehicle weight - which means less material to dampen sound - noise and vibration reduction is an essential component of modern day vehicle design.

One of the main contributors to noise and vibration is friction from two mating components. Without proper lubrication, the friction can cause squeaks, groans and vibrations that can be heard or felt in the cabin of the automobile. The DECC Company applies a variety of coatings, to numerous substrate types, to help mitigate this problem.

  • PTFE Coatings: PTFE (Polytetrafluoroethylene) is a fluoropolymer that provides a low coefficient of friction that prevents the scoring, galling, or sticking of mating components, which can ultimately eliminate squeaks and vibration. Some PTFE coatings, such as Henkel's Bonderite S-FN 310A & Bonderite S-OT 310B, have lower curing temperatures and can be applied to plastic, silicone or rubber components. 
  • Molybdenum Disulfide and/or Graphite: Graphite and molybdenum disulfide are inorganic solid based lubricants that can be used as standalone coatings or in conjunction with PTFE, such as Whitford's Xylan 1052. Because of their chemistry, these dry-film lubricants can transfer coating to the mating component, resulting in two lubricating surfaces. Dow Corning's Molykote D-708 is a great example of this type of coating. 

Squeak Reduction for Furniture

Squeak reduction is also common issue in the furniture industry. To reduce noise caused by friction, DECC applies PTFE coatings to office furniture components, particularly chairs. Furniture noise reduction coating solutions allow for quiet adjusting of ergonomic seating mechanisms and chair height. In addition to reducing noise, these coatings help add life to the furniture parts that experience the most wear.

Additional Benefits of Noise Reduction Coatings

The coating DECC applies coatings have benefits beyond reducing squeaks and groans as they can also help to minimize wear and extend the life of the part. This, in turn, leads to a decrease in costs associated with both repairs and part replacement.
