Wet film gauge for conformal coating thickness measurement. Wet film measurements are for conformal coatings where the dry film thickness can only be measured destructively or through the over-application of conformal coating. The wet film gauges are applied to the wet conformal coating; the teeth indicate the coating thickness.
The ability to gauge thickness measurement without requiring access to both sides of the test piece, offers this technology a multitude of possible applications. Paint thickness gauges, ultrasonic coating thickness gauges, digital thickness gauges and many more options are available to test plastics, glass, ceramics, metal and other materials.
Volume solid is the term that indicates the solid proportion of the paint on a volume basis. For example, if the paint is applied in a wet film at a 100 μm thickness and the volume solid of paint is 50%, then the dry film thickness (DFT) will be 50 μm as 50% of the wet paint has evaporated.
Determining the fineness of a paint's grind is important, because too coarse a grind may reduce the paint's color uniformity, gloss, and opacity. [7] The Hegman gauge is widely used for this purpose because it requires minimal skill and only a few seconds' work.
Each bar will give a "theoretical wet film thickness" or, in other words, the thickness of the coating that should remain on the drawdown card after application. Even with high manufacturing tolerances, the actual wet film thickness can vary from 50% to 90% of the gap. There are multiple types of bar applicators, their forms and uses are shown ...
Slot-die coating is a non-contact coating method, in which the slot-die is typically held over the substrate at a height several times higher than the target wet film thickness. [23] The coating fluid transfers from the slot-die to the substrate via a fluid bridge that spans the air gap between the slot-die lips and substrate surface.
