Summary for coating thickness gauge Discussion
Looking for a coating thickness gauge, Hank asked for equipment to measure two paint layers on ABS plastic, each about 15 microns thick, with at least 2-micron resolution on a curved surface. Jan Rijn replied that such equipment exists, but said his own trials showed results were not always correct when compared with destructive electron-microscope methods, and in his view there was not good equipment for this problem. He suggested a workaround: place small steel plates on the product before painting, then measure the coating thickness on those plates. Tyrone L. Caley pointed to Paul N. Gardner as a good source for film gauges and said that if they do not have it, it is probably not worth having; he also mentioned using a Quanix 1500 gauge. The thread later shifts to unrelated RFQs for wet film thickness gauges.

- 1, 2-layer painting on ABS plastic substrate,
- 2, each layer around 15 micron,
- 3, to a resolution of at least 2 micron
- 4, the surface is curved, but can find areas of 1 cm2 not quite so
- 2, each layer around 15 micron,
Thanks for any info.

A. Dear hank, There is such equipment on the market. I have tried out but the results are not always correct when I compare it with a destructive method under the electron microscope. At this moment there is not good equipment for your problem in my view. I can give you a hint. Put little steel plates on your products. Paint the product and measure the layer thickness. Good luck.

GARDCO = Paul N. Gardner Co.
A. A good source of film gauges is Paul N. Gardner. [Pompano Beach, FL]. If they do not have it is is probably not worth having.
I use 0-200 mil Quanix 1500 gauge.
