Defelsko PosiTest AT-M Manual Adhesion Tester

DeFelsko devised PosiTest Adhesion Tester for quality inspection on adhesion of a coating or several coated sample of any paint product is measured by assessing the minimum tensile stress needed to detach or rupture the coating perpendicular to the substrate.

Then the DeFelsko PosiTest is attached to the loading fixture and is then aligned to apply tension perpendicular to the test surface. The force that is applied gradually increases and is monitored until a plug of coating is detached, or a previously specified value is reached
