Application
Constant and defined film thicknesses is a precondition for testing and analysis of coating materials and coatings. Many properties of these materials depend on the film thickness.
It is important to know that for physical reasons the maximum achievable wet film thickness is not equal to the gap height. The following guidelines apply:
| Gap height | Wet film thickness |
|---|
| 15 - 100 µm (0.59 - 3.94 mil) |
about 50 % |
| above 100 - 300 µm (3.94 - 11.81 mil) |
about 60 % |
| above 300 - 500 µm (11.81 - 19.69 mil) |
about 80 % |
| above 500 µm (19.69 mil) |
up to 90 % |
For the choice of the correct gap height please also consider that the dry film thickness obtained can be less than the wet film thickness depending on the weight percent of solids.
There are wedge-shaped and uniform applications. For wedge-shaped applications, we offer the ZUA 2000 and ZUA 2002 Universal Applicator. There is a wide choice of uniform applicators from wire-bar, profiled, semi-circular, 4-sided up to universal applicators.
