For the development of new primers outstanding adhesion results to various substrates shall be obtained. One material may show different end results even when using the same primer. It depends on the previous processing of the material and, for example, whether it is a syndiotactic or atactic polymer. To evaluate the suitable primer for plastics, it is usually applied on the plastic and is then coated by a varnish or another finish. These specimen generally undergoes the cross-cut-test. The adhesion then is verified with an adhesive tape. This fast test only provides information on sufficient or insufficient adhesion. A detailed distinction as to the particular adhesion strength is not available. Here, the Adhesion Analyser LUMiFrac come into operation. This multisample measuring instrument, featuring easy operation and measurement, provides the user with the adhesion strength in Newton, for 8 samples simultaneously.
