The simple design and an absolutely straightforward operation make it possible for the practitioner to use the adhesion tester as an instrument for daily adhesion tests. Using adhesive with rapid curing, the tests can be performed by the user in the shortest possible time.
The pull-off type adhesion tester is designed for measure the adhesion value of paints and other coatings on the base and between layers or cohesive materials. The tensile adhesion tester is manufactured according to EN13144 and ISO 4624.
The testing with the mechanical tensile adhesion tester is performed in the following way. On the testing cover a dolly is glued and, after the glue is dried, it is pulled-off with the spring-system of the device. The force which is applied for pulling-off the glued dolly is displayed as a numerical value on the scale of the device. This value is the value of adhesion.
Operation
- Turn the top knob of the adhesion tester counter-clockwise to release the gripping mechanism and the spring.
- Now screw the adhesion tester (thread at the bottom) onto the measuring probe until the device reaches the surface to be tested.
- Turn the top knob clockwise until the measuring head is released from the test surface. You can read the tearing force from scale 1 or 2, depending on the measuring probe used.
- If the measuring probe has not been separated from the surface, turn the knob counter-clockwise to release the spring mechanism and remove the device from the measuring probe.
- Separate the measuring head from the surface, using a chisel and hammer.
- If the measuring probe has been separated from the surface, unscrew it from the device, using the wrench.
- Clean from the surface of the measuring probe any glue and paint residues or splinters.
