How is DFT measured in paint?
Dry film thickness can be measured on either magnetic steel surfaces or non-magnetic metal surfaces such as stainless steel or aluminium using a digital coating thickness gauge. The principle of electromagnetic induction is used for non-magnetic coatings on magnetic substrates such as steel.
What is DFT in paints?
Dry film thickness (DFT) is the thickness of a coating as measured above the substrate. This can consist of a single layer or multiple layers. DFT is measured for cured coatings (after the coating dries).
How coating thickness is measured?
Magnetic paint gages are used to nondestructively measure the thickness of a nonmagnetic coating on ferrous substrates. Most coatings on steel and iron are measured this way. Magnetic gages use one of two principles of operation: magnetic pull-off or magnetic/electromagnetic induction.

How is DFT measured in dry film testing?
DFT – (DRY FILM THICKNESS) – TESTING SERVICE Dry film thickness (DFT) is the thickness of a coating as measured above the substrate. This can consist of a single layer or multiple layers. DFT is measured for cured coatings (after the coating dries).
How is DFT related to the durability of a coating?
Durability of a coating is function of DFT, whereas the thickness of an individual coating layer in a coating system and the total system DFT reported specifies the coating’s durability. Types of DFT gauges include: Magnetic pull-off (Type I) Constant pressure probe (Type II)
Which is the best standard for DFT test?
Standards Used for DFT Measurement Four main standards used for DFTtesting are discussed in this article. SSPC-PA 2 (Measurement of drycoating thickness with magnetic gages) Australian Standard AS 3894.3 (Sitetesting of protective coatings, Method3: Determination of dry film thickness)
Are there industry standards for industrial paint DFT?
A. There is no industry standard for industrial paint DFT. On the other hand, most manufacturers have their own set of standards. These standards are driven by such factors as chemical and physical exposure conditions, value and finishing costs for their products.
