What is Dry Film Thickness (dft)?
Dry Film Thickness (dft) is the thickness of a coating when dry, expressed in mils. A mil is a measurement used to determine the thickness of a coating. One mil equals one thousandth of an inch. 1 mil = .001 inch (1/1000). For comparison purposes, 4 mils is approximately the thickness of one sheet of standard paper. Many plastic trash bags have a thickness of about 1.0 mil although heavy duty (so-called “contractors”) bags may be about 3.0 mils.
