Technical melamine-formaldehyde (MF) impregnation resins were investigated by 1H-NMR-spectroscopy (1H-NMR), gel permeation chromatography (GPC), gas chromatography (GC), rheology, and chemical analysis. By the use of these methods more information about the molecular structure of the resins can be obtained. The combination of analytical tools can help to improve the development and application of impregnation resins. The results presented here are only examples for the use of modern analytical tools for the investigation of impregnation resins. All shown methods can be used for the analysis of e.g. urea- or phenol-formaldehyde impregnation resins as well.
