The initial adhesion tester is an instrument used to measure the initial adhesion force on the surface of materials. Initial adhesion refers to the adhesion force that an adhesive exerts on the surface of the object being adhered in a very short period of time. This type of testing is usually applied to pressure-sensitive tapes, labels, protective films, and other products, and is very important in the production, quality control, and research and development processes of these products.

The working principle of the initial adhesion tester is usually to use a standard test piece (or object to be adhered), use a certain weight of weight to fall from a certain height within a specified time, act on the test piece, and then record the maximum angle that the weight can stick the test piece up. This angle is the magnitude of the initial adhesion force.

There are many types of initial adhesion testers on the market, and different brands and models of instruments may have differences in testing methods, operating interfaces, data processing, etc. However, their core functions are all to evaluate the initial adhesion performance of materials.
