Layer thickness
The coating thickness gauge is used to measure the dry film thickness of the paint. Dry film thickness measurement is probably the most important measurement in the coating industry. A coating thickness gauge provides information about the expected life of a substrate and the efficiency and visual characteristics of the product. Thanks to this data, you can be sure that your product complies with a whole range of international standards.
In order to know the process variables during the application of the paint, it is wise to check the layer thickness while it is still wet. This provides an indication of the expected dry layer thickness.
Roughness
The surface profile gauges are used to measure the profile height of a surface. The profile height of a surface affects the overall performance of a coating and determines aspects such as adhesion, coverage and the total volume of the coating used. Larger profiles require more coating to ensure adequate coverage, so that there are no uncoated peaks where rust spots can develop. Smaller surface profiles may have an insufficient adhesive layer to obtain adequate adhesion, which can lead to the premature development of coating defects.
Adhesion
Adhesion tests after the coating process help to assess the bond strength between substrate and coating or between different layers of coating or even the cohesive strength of certain substrates.
Routine testing is part of the inspection and maintenance process and helps identify possible coating defects. The adhesion tester is a simple quantitative method to determine a definitive adhesion value. In most cases, test plates are used. The test plates are sprayed with the object, so that the test plate is treated in the same coating with the same conditions as the object itself. We let the test plate dry for 2 weeks, so that it has hardened properly.
