The instrument meets the requirements of GB/T 5210, ASTM D4541/D7234, ISO 4624/16276-1, etc. It is the first automatic pull-off tester in China and has the characteristics of simple operation, accurate data, low maintenance cost and low cost of supporting consumables. Adhesion testing between different coatings in some concrete base coats, anti-corrosion coatings or multi-coat systems. The test sample or system is applied to a flat surface having a uniform surface thickness. After the coating system is dried/cured, the test column is directly bonded to the surface of the coating with a special adhesive. After the adhesive is cured, the coating is pulled at a suitable speed by the instrument to test the force required to break the adhesion between the coating/substrate. It is worth noting that the tensile force of the interfacial interface (adhesion failure) or the tensile force of the self-destruction (cohesive failure) is used to indicate the test results, and the adhesion/cohesive failure may occur simultaneously.
