Glossary of surface technology


Fluorination is the introduction of fluorine into organic compounds by means of fluorine-containing process gases. It is a special case of halogenation. In the reactions in question, hydrogen atoms are primarily replaced by fluorine atoms. This is a chemical reaction and not a coating. Being easy to manufacture and low-weight, plastics are becoming increasingly important in various industrial sectors. The simpler the molecular structure, the cheaper the raw materials. But the further processing of these plastics is often problematic because of their non-polar surface. Industrial manufacturing processes such as painting, coating, flock-coating, bonding, and printing require good adhesion. A polar surface is essential to make chemical bonding possible. During fluorination, surface properties are created which have a very polar character without attacking the base material. Long-term tests have shown that, compared to conservative treatment methods, the surface tension decreases only insignificantly even after several weeks’ storage.
