In this paper, the results of research of structural changes that occur during in furan resins with different content of furfuryl alcohol by UV radiation and atmospheric air are presented. The research was carried out by transmission method (KBr pellets), using FTIR spectrometer Excalibur 3000 for the three samples of furan resins with different content of furfuryl alcohol. As a result of UV radiation and oxidizing atmosphere only the sample of the resin Kaltharz 8616 remained liquid. Two others (Kaltharz U 404 and Kaltharz 8117) were cured after 1
