Meyer, B; Nunlist, R

The work shows that adhesive and foam resins differ significantly in qualitative and quantitative composition, and that the differences in the C-13 NMR spectra can be readily recognized, even by an untrained person. The fingerprints of resins are so characteristic that NMR operators who are not familiar with urea-formaldehyde resin chemistry, can rapidly learn how to distinguish between particleboard or plywood adhesives and foam resins, as well as between different manufacturers and individual batches. Thus, the NMR method lends itself extremely well to quality control.
