Peel testing can be used to evaluate the adhesion properties of coatings after they have undergone fatigue testing (ISO13003) and/or weathering (ISO12944). Fatigue testing involves subjecting a coating to repetitive loading, which can cause stress and strain on the coating and can potentially lead to coating failure. After the fatigue testing is completed, a peel test can be performed to determine if the coating has failed and to evaluate the degree of adhesion loss. Peel testing after fatigue loading can provide valuable information about the coating’s performance and durability under realistic loading conditions. By comparing the peel strength of the coating before and after fatigue testing, it’s possible to determine if the coating has degraded and how much adhesion loss has occurred. It’s important to note that fatigue testing and peel testing are two different types of tests that evaluate different aspects of coating performance. Fatigue testing measures a coating’s resistance to failure under cyclic loading, while peel testing measures the adhesive strength of the coating. Therefore, it’s recommended to combine both tests to get a full understanding of the coating’s performance and durability. It’s also important to note that the procedure of peel testing should be the same as it was before fatigue testing, to ensure that the results are comparable. It’s also recommended to use the same adhesive tape, the same equipment and the same operator to ensure that the results are accurate and consistent. In summary, Peel testing after coating fatigue is a way of evaluating the adhesion properties of coatings after they have undergone fatigue testing. By comparing the peel strength of the coating before and after fatigue testing, it’s possible to determine if the coating has degraded and how much adhesion loss has occurred. It’s important to combine both tests to get a full understanding of the coating’s performance and durability and to ensure consistency in the peel testing procedure.
