Studies on polycondensation core binders conducted at the ICRI in cooperation with the Institute for Foundry Science, Cracow, have been reviewed with particular reference to the elucidation of the course of the reaction of urea withf ormaldehyde and furfuryl alcohol (FA). These studies were commercialized and resulted in industrial production of numerous core binders for producing coresat room temperature, FA-modified urea-formaldehyde Karbafur Z, urea-phenol-formaldehyde Hapol for cores to be produced at 160—260°C, FA-modified urea-formaldehyde Karbafuryl G-25, urea-phenol-formaldehyde FM-50,153 M and 153 MBZ, AF-modified phenolurea-formaldehyde Molfur and Molfix, etc. The processes were commercialized at the Plastics Plant, Pustkow, and at the Chemical Works „Gamrat”, Jasło. The binders have been applied in various foundries (FSO, Żerań; FSM, Skoczow; Fabryka Łącznikow, Radom-Podkanow, the Metallurgical Plant „POMET”, Poznań, and many others).
