pull-off testing

Pull-off testing is a method used to measure how strongly a coating or material adheres to a surface. It involves attaching a device to the coated surface and gradually pulling until the coating or the bond between the coating and the substrate fails. The force required to detach the coating is recorded, providing a quantitative measure of adhesion strength. This test helps assess the durability and quality of coatings in industries like construction, manufacturing, and automotive, ensuring they meet safety and performance standards.
