DeFelsko PosiTest AT-A Automatic Adhesion Tester

DeFelsko PosiTest Automatic Adhesion Tester AT-A is an innovative gauge that combines user convenient and repeatability for quality inspection on adhesion of a coating or several coated sample. This adhesion tester is applicable for any paint product on any surface and automatically assess the minimum tensile stress needed to conforms to international standards including ASTM D4541/D7234, ISO 4624/16276-1, AS/NZS 1580.408.5 and others.

Thanks to its electronically controlled hydraulic pump action, it applies smooth and continuous pull-off pressure that will greatly reduces user effort and the risk of influencing the pulling process. Compared to other method, DeFelsko PosiTest maximizes the tensile stress, as the test is done by securing loading fixtures (dollies) perpendicular to the surface of a coating with an adhesive. 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

Your investment on DeFelsko Automatic Adhesion Tester PosiTest AT-A will allow you to test indoors and outdoors surface and in all types of weather. BE advised that after the pull-off test, the dolly and coated surface should also be examined as many National and International standards such as ASTM D4541 and ISO 4624 do require the nature of the fracture to be recorded. DeFelsko PosiTest are applicable to test rugedness of coating on concrete, boiler pipes, steel structure, tubings (depends on the curvature and surface uniformity), durability of painting or protective flim, remaining life assesment of coated steel prducts and many more.
