EN The first part of this paper deals about chemical surface pre-treatments of zinc and the impact of alternative pre-treatments for adhesion of organic coating. The second part is devoted to the experimental part, and there was created several surface pre-treatments of hot-dip galvanization and subsequently applied two kinds of organic coatings. The objective was a comparison of chemical pre-treatments, mechanical pre-treatment and the effect each of them on the adhesion of the organic coating. It was created seven variants pre-treatment of hot-dip galvanization surfaces. Adhesion of these systems was investigated by pull-off test according to ČSN EN ISO 4624, adhesion test with X-cut tape test according to ASTM D 3359, adhesion crosscut test according to ČSN EN ISO 2409. In this work was investigated two coating systems at six chemical and one mechanical pre-treatment of the surface of the hot-dip galvanization.
