Résumé : This study is based essentially on adhesion between polymer and metallic industrial surface and artificial honeydew. This measurement of adhesion will be carried out with a pegosity (tack) test. Actually, the objective of this study is to find experimentally the influence of various parameters like composition, nature and water content of honeydews. The aim of this work is to highlight the importance of surface treatment on adhesion energy. In the first part, a fine characterization has been carried out on industrial surfaces and artificial honeydews. This study has shown the heterogeneity of the surfaces as far topographical and chemical aspects are concerned. In the second part, the measurement of adhesion has been carried out on substrates and honeydews with the help of a pegosity (tack) test using two types of geometry. The results indicate clearly, that taking into account the composition of honeydews, the nature of the surfaces plays an important role in adhesion energy.
