WebNov 16, 2016 · Powder Coating Film Thickness Testing. A film thickness test determines the thickness of the powder on the part once it’s been cured. This is generally confirmed with a Dry Film Thickness gauge. These gauges are fairly affordable and easy to use. A common range to look for is 2-3 dry mils (thousandths of an inch). WebThe slower rate of drying offers the advantage of increased film thickness uniformity across the substrates. The fluid dries out as it moves toward the edge of the substrate during the spin process. This can lead to radial … Web4.2 Thickness non-uniformity . Figure 4.3 shows the non-uniformity in film thickness as measured by . Filmetrics F50. Except for the anomaly in non-uniformity for deposition done at 20 W, there is almost linear increase in non-uniformity in film thickness with increasing power.
