Pushhen drawing spindle 20mm is the top supporting the Pushhen drawing adhesion Tester, the size is 20mm, and the testing force range is 100~3000psi.

The test sample or system is applied in a uniform thickness to a flat plate with a uniform surface structure. After the coating system has dried/cured, the test post is bonded directly to the coated surface with a special adhesive. After the adhesive is cured, put the bonded test combination on the PS2658 digital display pull-off adhesion Tester. The Tester pulls the test column from the coating uniformly and at a speed not exceeding 1MPa/s through the hydraulic pump. The required force is directly displayed through the LCD of the instrument, so as to test the force required to break the adhesion between the coating/substrate.

It is worth noting that the test results are expressed by the tensile force between the failure interfaces (adhesive failure) or the tensile force of self-destruction (cohesive failure), and the adhesion/cohesive failure may occur simultaneously.
