WebJul 1, 2013 · Typically, a thickness of about 1.5 to 2.0 mils will work well. The more geometry you have on the part, the more variance you will likely have, as the part shape will affect the film uniformity. For parts that must handle harsh environments, you may need more film thickness. Outdoor performance will require a thicker minimum, therefore a ... WebThe wet layer film thickness has poor reproducibility. This is due to the shearing rate of the solution impacting the final film thickness. Ideal Uses. Doctor blading is a technique that is well suited for large-scale coatings. The technique is also well suited for creating thicker films from a viscous solution. WebThe calculation is: Wet film measured in mils (.001) x percent solids by volume = DFT. Example: 5 mils wet x 35% solids by volume = 1.75 mils DFT.
