Coating Reduces Noise and Vibration in Cars

PPG Industries (NYSE:PPG) has introduced Audioguard coating - a waterborne, spray-applied coating that provides vibration damping and reduces vehicle noise - for commercial coatings customers. A recipient of the PACE Award for supplier product and process innovation, Audioguard coating offers commercial original-equipment-manufacture body builders a solution for structural vibration and noise reduction in cabs, under hoods, inside wheel wells and on interior panels.

"Audioguard coating is made of a proprietary combination of laminar, fiber and resin that hardens into a tough coating material," said Dave Chapman, marketing director, PPG commercial coatings. "Because it's waterborne, it's a zero-VOC product and a very ecologically sound way to address vehicle noise and vibration issues."

According to Chapman, Audioguard coating is particularly suited for fire and emergency equipment applications, as it reduces siren and road noise and provides patients and emergency technicians with a lower-decibel interior environment. It can be applied by spraying onto exposed surfaces or by spray wands into restricted areas, and it is effective for numerous noise- and vibration-reduction applications.

Audioguard coating offers:

  • superior sound and vibration damping
  • a one-component waterborne product
  • a zero-volatile organic compound and non-hazardous air pollutant coating
  • air drying or heat curing
  • chip, crack and mar resistance
  • thermal insulating properties
  • a high performance-to-price ratio
  • approval for OEM automotive use
  • the ability to help OEMs meet passenger compartment noise-abatement requirements
