A1 - Hielscher, Stefan A1 - Grunwald, Daniel A1 - Beck, Uwe T1 - Determination of coating properties by using analytical centrifugation N2 - The majority of all products have coated surfaces designed to fulfil different requirements. Building constructions are exposed to external influences like a wide temperature and humidity range, rain and UV radiation to name a few. The extension of machine life for metal cutting tools, like drills or milling cutters is another field of application for coated surfaces. The surfaces have to be modified in a way to maintain their specific functionality. Although adhesion testing of coatings is of great interest, it is still a challenge to obtain reliable quantitative results and to meet economic requirements. In this talk we deal with the curing behaviour of different 2-component epoxy paint systems for corrosion protection of metal constructions. After preparation of specimens the strength was determined in specified time intervals during curing. It could be shown that epoxy paints differ significantly on curing time as well as final strength. The second experimental study deals with coating systems on glass fibre reinforced plastics which are used for wind power turbines to reduce abrasive wear and ice adhesion for aerodynamic and safety reasons. All measurements have been carried out by CAT-TechnologyTM (Centrifugal Adhesion Testing), which uses the radially directed centrifugal force as test-load. The multi-sample test instrument analyses up to eight test specimen under identical testing conditions. By varying the rotational speed (100 rpm up to 13,000 rpm), forces from 0.1 N to 6.5 kN are applied. Upon reaching the critical rupture force, the stamp separates from the substrate and a sample related IR-signal is sent from the spinning rotor. For each test specimen breaking force is calculated and displayed in real-time. The innovative measurement principle meets the requirements of DIN EN 15870 and ISO 4624.
