How Thick Is A Coat Of Paint? Traditionally a destructive test method is used to determine paint thickness. Today, the primary purpose of ultrasonic testing is to non-destructively measure the TOTAL thickness of the paint system, typically in the range of 3 to 5 mils (75 –125 μm). How thick is a micron of paint?
What Is DFT And WFT? The volume solids content is the percentage of the formulation that is non-volatile and will remain on the surface after the coating dries and cures. Without thinner: Wet Film Thickness (WFT) = Dry Film Thickness (DFT) ÷ Percent Solids by Volume. Example: Specified Dry Film Thickness = 3 – 5
How Does A Coating Thickness Gauge Work? A permanent magnet is mounted on a balanced arm and the force required to pull this magnet from the surface of the coating is a measure of the thickness of the coating. Force is applied through a helical spring attached to the balanced arm at one end and
