PAT model GM04/40kN Adhesion Tester

With its 40kN pull force, this is the most powerful manual manual tensile adhesion tester in the range. It is designed for testing of thermal sprayed coatings on test panels, on the sprayed component or testing together with a jig in accordance with ASTM-C633 (two test cylinders glued together) designed particularly for testing with Ø50mm test elements and with the square 50 x 50 mm test element for adhesion testing of tile adhesives and other cementitious materials. The equipment complies with ISO 4624, ASTM D 4541, EN 1542 and ASTM C633.
