Jul 19, 2024 · 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). The thickness of a coating depends on the application and type of process employed.
A dry film thickness (DFT) gauge often referred to as a coating thickness gauge, can be used to measure the thickness of any of these coatings when dry. Measuring dry film thickness is important when assessing cost, quality and service life of the coating.
Jan 21, 2020 · Dry Film Thickness (DFT) When the required calculation is in reverse and you are looking to obtain the dry film thickness (DFT) the following formula applies; WFT x VS / 100 = DFT so using the same numbers as we did above working out the wet film thickness the equation looks like this (150 x 60 / 100) = 90 microns DFT). Volume Solids (VS)
Elcometer's has a comprehensive range of Dry Film Coating Thickness Gauges and Paint Meters to meet all of your coating inspection requirements
A coating thickness gauge (also referred to as a paint meter) is used to measure dry film thickness. Dry film thickness is probably the most critical measurement in the coatings industry because of its impact on the coating process, quality and cost.
Coating thickness, paint thickness, or dry film thickness (DFT) is an important variable that plays a role in product quality, process control, and cost control. Measurement of film thickness can be accomplished by selecting the best mil gage for the particular application.
The Paint dry film thickness measurement is addressed on SSPC-PA 2 and provides information to how to average the readings and determine DFT acceptability. Let's start with an example, you review the customer coating specification and see that requirements for DFT 9-12 mil.
The components are often written as a ratio or as a percentage and can be used to predict the dry film thickness (DFT) when the wet film thickness (WFT) is known. The predicted DFT can be calculated from the WFT using the following formula: DFT = WFT x Volume Solids
Dry film thickness (DFT) is the thickness of a coating or paint film after it has dried and cured on any type of substrate, whether ferrous, non-ferrous, or others.
Applied Technical Services performs DFT testing for painting and coatings to uncover information on the coating’s quality and performance. What is Dry Film Thickness and Dry Film Thickness Testing? Dry film thickness testing evaluates the thickness of a single layer or multiple layers of coating.
