Abstract

A range of commercial paint binders and two‐pack elastomers containing silícone materials have been investigated by ^29^Si Fourier transform nuclear magnetic resonance spectrocopy at 17.76MHz. In order to obtain good quality spectra within a minimum of time period, a relaxation agent was used to supress nuclear Overhauser effects, and to improve the relaxation times of the silicon nuclei.
