Dry film thickness คือ
WebA 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. A coating which is too thick means that excessive material is being used, increasing ... Web• Measure the dry film thickness (dft) obtained from a measured wet film thickness (wft). • Calculate volume solids as follows: (measured dft x 100) ÷ measured wft. The coating should be applied at a wft, as recommended in the techni-cal data sheet, and allowed to dry/cure as scheduled (typically 7 days at 23 ±1 C [73±2F) before the

WebNov 16, 2016 · A dry film thickness gauge is a tool or instrument used to measure the dry film thickness on a metal or nonmetal substrate and compare it to approved standards. … WebFor example, if a coating specifies you apply it at 500 microns WFT (Wet Film Thickness) and the volume solids of the product are 50% then once dry the DFT (Dry Film Thickness) reading will be 250 microns. Some coatings are 100% volume solids which means nothing thickness will be lost between WFT and DFT.
