Abstract: A binder composition for use in producing molds, which contains a binder obtained by the polycondensation of monomers mainly comprising furfuryl alcohol, urea and an aldehyde and wherein a difference (A-B) between the weight percentage (A) of the feed furfuryl alcohol and the weight percentage (B) of the unreacted furfuryl alcohol, both based on the binder, ranges from 5.0 to 60.0. The composition serves to accelerate the hardening of the binder without worsening the working environment.
