Pull-Off Method Tester

The pull-off adhesion tester uses mechanical or hydraulic devices to vertically stretch bonded specimens, measuring the maximum force required to peel coatings or adhesives from the substrate. This instrument is used to evaluate adhesion strength and is applied in quality control and research and development within the coatings and adhesive industries.
Selection
When selecting, pay attention to the range matching the strength of the tested material, ensure the accuracy meets testing standards, verify that the fixtures are compatible with the specimen shape, require the equipment to have data recording capabilities and a calibration certificate, and ensure the operating interface is simple and user-friendly.
