Pull Off Adhesion Tester (Automatic)

Pull Off Adhesion Tester (Automatic) Pull-off adhesion assesses the resistance of paints adherence to a substrate. A dolly is glued to the coating surface, after the glue is cured, a testing apparatus is attached to the loading fixture and aligned to apply tension perpendicular to the test surface. The force applied is gradually increased and monitored until either a plug of coating material is detached, or a specified value is reached. Our Automatic tester applies smooth and constant pressure to make testing easy and ensure repeatability. The pull force can be preset and the internal memory stores maximum pressure, rate of pull, test time and dolly size. It evaluates the adhesion (pull-off strength) of a coating by determining the greatest tensile pull-off force that it can bear before detaching. Breaking points, demonstrated by fractured surfaces, occur along the weakest plane within the system consisting of dolly, adhesive, coating layers and substrate.
