WebThe wet film gauge should only be used while installing the air barrier to confirm the wet film thickness. Cutting out a piece of the membrane and trying to measure the dry film thickness after the air barrier has fully cured out is very inaccurate. One of the most reliable ways to measure dry-film thickness of an air barrier is to use a ... trusted express incWebNov 1, 2004 · The curable thickness of the coating cured with a conventional mercury lamp led to a maximum of ca. 70 µm. With the UV-A lamp, a significantly higher curable film thickness was measured. This is probably due to the higher penetration of UV-A light into the film (Figure 6). philip ratnerPowder coating thickness measurements can be taken before and after curing.
