 This test determines the adhesion of a coating by measuring the tensile stress needed to remove a test dolly from the coating. A continuous pressure build-up of 1 MPa per second is recommended and the test should also be completed within 90 seconds. This can only be guaranteed by using an automatic adhesion gauge such as the Elcometer 510. This device is portable and easy to use. It provides an accurate numeric figure for the coating adhesion (in MPa, psi, N/mm2 or N) and records the increase in load over time in the form of a graph.
