Coating thickness

I need to find out the thickness of a Polyurea coating being applied to foam backing. Does anybody have experience with this?

Thanks.

Re: Coating thickness
We have successfully done this sort of measurement using ultrasonic thickness gages and delay line transducers. If the coating is reasonably smooth, bubble-free, and at least 0.5 mm thick, we may be able to help you. The potential limitations are rough outside surfaces or the presence of air bubbles within the coating, both of which will scatter the sound waves.

oved signal to noise ratio, characterize, size and analyze defects better with access to several wave mode views and save raw FMC data for higher quality analysis.  Some of the benefits are:
  • Beautiful Image! Easier to understand what you're looking at
  • Completely focused in entire image or volume
  • Much easier to define setups before inspection
  • Easier to decipher geometry echoes from real defects
  • Oriented defects (e.g. cracks) are imaged better
  • See image from different wave modes from one FMC inspection
  • FMC data can be reprocessed/analyzed without going back to the field
