Adhesive joints in building envelope are particularly suitable for the fragile material glass. For bonding of glass with other materials exists a wide range of adhesive products but for a very good adhesion especially the quality of the substrate surface is important. Thereby the surface structure, inherent moisture and dirt and their reactivity have a decisive influence on the durability of the adhesive bond. The surfaces of the materials and thus their adhesive behaviour can be modified by specific cleaning and surface treatments. Such procedures should afford a good wettability of the adhesive on the substrate and they can provide energetically active centres on the surface.
Mechanical methods such as milling, grinding, polishing and sandblasting are especially suitable as pre-treatment for metallic materials. Physicochemical methods like flame pyrolysis and atmospheric pressure plasma cause on different substrates a cleaning and activation effect on the surfaces.
This study investigates the influence of process parameters of the different surface modification methods on various materials.
