Klebeprobe

Klebeprobe is a German term that translates to "adhesive test" or "tape test." It refers to a method used to assess the adhesion strength of a coating or paint to a substrate. This test is commonly employed in various industries, including automotive, manufacturing, and construction, to ensure the durability and performance of applied finishes.

The Klebeprobe typically involves applying a specific type of tape with a known adhesive strength to the surface of the coated material. The tape is then pressed firmly onto the surface to ensure good contact. After a short period, the tape is rapidly removed at a specific angle. The success of the test depends on the amount of coating that remains adhered to the tape after removal. If a significant portion of the coating is lifted with the tape, it indicates poor adhesion.

There are different standardized methods for conducting a Klebeprobe, often varying in the type of tape used, the application pressure, and the speed and angle of removal. These variations allow for the testing of different adhesion strengths and coating types. Visual inspection of the substrate after tape removal is a primary way to evaluate the results, though sometimes specialized equipment might be used to quantify the amount of coating removed. A successful Klebeprobe demonstrates that the coating is adequately bonded to the substrate, ensuring its longevity and resistance to peeling or delamination under normal use conditions.
