    carried out in association with Urea, Phenol or both. The series of resins obtained, having Furan ring (C 4 H 4 O) in chains, at different PH conditions and varying compositions are called Furan resins. These resins (binders) and acids (catalysts) make a two part no bake self-set system (popularly known as FNB in foundry terms) like


    Both analysed resins behave in the same way at higher temperatures. At the 20 oC–50 oC temperature range, it is mainly the intensity of bands associated with C-H bond vibrations that change. A further increase of the temperature causes the structure of the resin to be modified within the range corresponding to furan ring vibrations.
