The improved Model B tester from Benz has automated the test process with microprocessor-controlled data acquisition. Designed to provide the expected internal bond strength for various types of paper, coated products and paperboard, this instrument measures the impact energy imparted to the specimen. The machine consists of a base, sample-preparation press, tape dispenser, dual-range pendulum (0 to 0.325 ft. lbs. and 0 to 0.650 ft. lbs.) and Digital Display. Internal Bond software is available.The specimen is held between the base and the anvil of the test fixture, using double-faced pressure-sensitive tape. One-inch-square specimens are prepared under calibrated pressure to insure uniform adhesion to the fixture and the aluminum angle. The impact force of the pendulum head striking the aluminum angle is displayed on the PC. precise results without operator interpretation - assures material quality time-saving reports - test results displayed on computer screen with previous results for comparison. increase testing-budget buying power - affordable, reliable design simple, fast testing - quick-release sample set-up tests a variety of products - user-selectable parameters The Model B also includes five sample bases, five sample angle holders, a knife-blade assembly, and pressure-sensitive tape.

Adhesive strength is measured for many purposes. Some bonds are designed not to break in use (e.g. construction materials), some are designed to allow separation in normal use (e.g. a foil lid), and others are designed to be resealed a number of times (e.g. resealable bag tape). Some things peel without a separate adhesive layer, such as an induction-welded foil, or grip seal bags, and some adhesive joins for security come apart but must not reseal. Adhesive bonding can be measured by tensile testing, shear testing or compression testing, but where there is flexibility in a joined layer, a peel test is appropriate. A universal tester can be used for any peel test. It will capture high frequency data points, and produce a characteristic curve that will show the strength and evenness of the adhesion. The advantage of using a Mecmesin universal tester is that it can also be used for adhesive shear and compression tests, or coatings pull-off tests
