Pull-Off Adhesion Tester

PROCEQ (Made in Switzerland) Pull-Off Adhesion Tester (5,620lbf)

Proceq Pull-Off Adhesion Testers produce accurate, repeatable results when testing bond, adhesion, or tensile strength of coatings, overlays, and substrate surfaces. The Testers are fully automated, with one-touch operation after programming and test disc preparation is complete. Feedback-controlled motors provide a constant, verifiable load rate that eliminates operator influence on load measurements. Every test parameter is verifiable and recorded by the included DY-Link software. The compact size of the Testers allows use in spaces with restricted access and easy operation on walls and overhead surfaces. Applications include the bond and strength assessment of concrete repairs and overlays, pull-off and adhesion strength of coatings bonded to concrete, the tensile strength of concrete surfaces, and adhesive strength of asphalt.

Programming is simple and can be performed on a horizontal surface prior to use on walls and overhead. Simply select the units of measure, test disc size, and load rate. To conduct the test, a specialized coring bit is used to cut the substrate material to match the size of the test disc. A standard epoxy-based adhesive adheres to the disc to the surface. The Pull-Off Tester is connected and applies perpendicular force until the test disc is pulled off and the maximum force required is recorded. Total testing time is less than 100 seconds for all applicable standards. Up to 80 tests can be performed on a single battery charge. Internal memory can store up to 100 measurements.

The Pull-Off Testers begin to measure as soon as any load is applied, and the load rate can be viewed in real-time when connected to a PC. The Testers provide a complete record of the pull-off test, confirming that the test was carried out in accordance with the applicable standard. Recorded parameters include the time/date of the test, test disc size, the maximum load applied, calculation of bond strength, applied load rate, test duration time, and failure mode. Failure modes include failure in the coating layer, between the coating layer and substrate, and failure in the substrate.

It has a maximum pulling force of 5,620lbf (25kN) for high-strength applications, including the tensile strength of concrete renovation and the bond and tensile strength of contentious repairs and overlays.

The Test Disc required varies according to material and application. The feet on the Pull-Off Testers are configured differently to accommodate the different sizes of Test Discs. Smaller test discs use a tripod configuration, a two-legged arrangement for larger test discs, and the accessory CTA-56 Adapter Plate is needed to accommodate 75mm and 100mm test discs. Proceq Test Discs require an M10 Draw Bolt. The M8 and M12 Draw Bolts are for use with Test Discs not supplied by Proceq.

A comprehensive range of test discs, draw bolts, and an adapter plate are available. Included with both models are a carrying case, battery pack, battery charger with a USB cable, 50mm aluminum test disc, M10 draw bolt, Torx screwdriver, DY-Link software, operating instructions, and calibration certificate.
