POSITEST-ADHESION-TESTER PosiTest Pull-Off Coating Adhesion Tester

The PosiTest adhesion tester determines the adhesion of a coating or paint layer to its substrate. This destructive adhesion test method works as follows; a metal dolly is glued to the coating or paint layer and is pulled from the substrate vertically with help of the hydraulic adhesion tester.

The pulling mechanism of the PosiTest adhesion tester is self-aligning to make sure the dolly is pulled perfectly vertical under every circumstance, producing reliable, repeatable measurements. Peeling of the dolly producing incorrect results is prevented with this mechanism.

The norm for adhesion testing prescribes the maximum pull rate, pulling too fast results in incorrect measurements. The adhesion tester is equipped with a pull rate indicator preventing the user from pulling the coating from the material too fast.

Simple

• Portable, hand-operated instrument requires no external power source – ideal for lab and field use
• Large, easy-to-read LCD
• Pull Rate Indicator – allows operator to easily monitor and adjust the rate of pull in accordance with international test methods
