The Touchstone 2 coating thickness gauge is easy to use and requires no couplant, it will work on rough surfaces in any condition. The usual criterion for determining the expected service life of zinc coatings is thickness: the thicker the coating, the longer the service life. Hi Diana, Importance of Coating Weight and Thickness Testing. The coating thicknesses required to equal 1 oz of zinc/ft2 of surface, are displayed in the Coating Densities table below. What should be the thickness? Was this answer helpful? Stripping, Microscopy, Weighing Before and After Galvanizing, or Magnetic Thickness Measurement. Zinc coating thickness (µm) = mass (g/m2) / zinc density (7.14) Example: zinc coating thickness measured on one side of the CGI sheet is 20 µm. Two different methods can be used to measure the coating weight of hot-dip galvanized steel. Coating Thickness Conversion Chart Abbreviations: µm – micrometer; mm – millimeter; In the Coating Thickness Conversion Chart, what is shown is the conversion of one metric unit into another. These paint thickness gauges offer fast, accurate and reliable profile measurement of paint and organic coatings providing essential information to optimize the production process. Learn how you can rely on our gauges for accurate thickness or coating … Every coating operation is different and there are many application … That answer looks like the density, 1.39 g/m 3, but I just took the (cubic) volume term and converted it to a weight per surface area by multiplying by the density to yield a mass per area term we call the film weight (or mass). Anodized coating produced in a non-chromic acid electrolyte. Each of these thicknesses, representing the same weight per unit area of zinc, would be expected to provide equivalent service life; i.e. The equation is the following: Total Thickness – Carrier Material Thickness = Coating Thickness The gauge can easily measure the total thickness of the material. Coating weights … Remember that 8625 states that the coating thickness should be called out by the customer. If that film of PET was a film of adhesive, we would say it has a coated thickness of 1 micron and a coating or coated weight of 1.39 grams per square meter. The thickness of various types of phosphate coatings will be of the order of 1 to 50 microns. DeFelsko PosiTest DFT Coating Thickness Gauge, Ferrous 0-40 mils Model: DFTF-C Your Price $495.00 USD Newsletter Signup: Sign up for Galvanizing Insights, the AGA's quarterly specifier e-newsletter. ß-ray Coating Weight. Some of the regularly used test methods that ATS carries ISO 17025 accreditation by A2LA are; ASTM D7091 (Nondestructive Measurement of Dry Film Thickness of Coatings Applied to Ferrous and Nonferrous Metals), ASTM A90 (Measurement of Coating Weight on Galvanized Articles), and ASTM B137 (Measurement of Coating Mass on Anodized Aluminum). Figure: Thickness of tin coating: This test determines the thickness and weight of tin coating on either side of plate. Thanks, Diana Couture Seattle Galvanizing. This calculator estimates the wet film thickness required to achieve a target dry coat weight. 22 Coating Thickness Weight oz/ft2 g/m2 mil µ 1/1000 1/1000 (in) (mm) Coating Thickness Weight oz/ft2 g/m2 mil µ 1/1000 1/1000 (in) (mm) 0.40 122.0 0.67 17.0 Hi, Wet Film Thickness. The coating thickness is controlled by air knives arranged above the strip. Improve Coating Quality and Reduced Production Costs with High-Accuracy, Repeatable Measurements.
