WEATHERING INVESTIGATION OF PVC COATINGS ON IRON SHEETS BY THE NMR MOUSE

A new kind of MOUSE-the NMR mobile universal surface explorer-makes NM R investigations possible on composites with ferromagnetic components, which were previously excluded from such studies, because inhomogeneo us magnetic fields are used in the first place. An example application is described, to relaxation measurements of polyvinylchloride (PVC) c oatings on iron sheets. It is demonstrated that new and artificially w eathered PVC coatings can be distinguished by means of their different transverse relaxation times.
