 As a result, the thickness of the coating needs to be checked regularly both after a change of colour or component and also during the normal application process. Otherwise, there is the risk of producing components that are not fully coated, where the amount of powder is too small, or of incurring unnecessarily high costs, where too much powder is used. It is particularly important to measure the coating before it is cured, in particular in corners and on edges, because any areas that have not been adequately coated can easily be rectified at this early stage.The thickness of powder coatings can now be measured easily, even on complex parts.© TQC
