Engineering calculation
Wet and dry film thickness calculator (WFT/DFT)
Estimate dry film thickness from a wet film, or determine the wet film required for a target DFT.
Open calculatorCalculation logic
DFT = WFT × effective VS / 100; WFT = DFT × 100 / effective VS.
Worked example
At 100 µm WFT and 50% effective volume solids, the expected DFT is 50 µm.
Before using the result
Use the volume solids after thinning from the material TDS and check the permitted DFT range. Part geometry and actual application losses are outside this conversion.
