Abstract
A resin compsn. comprises furfuryl alcohol (I) and an aromatic hydrocarbon-HCHO resin (II) soluble in (I). Pref. the compsn. contains is not >10 wt. % pref. is not >5 wt. % (II). (II) is esp. a toluene-HCHO resin. A urea-HCHO may additionally be included. The compsn. is suitable for coating and core moulds. It contains practically no free HCHO, phenol or nitrogen. The resin can be hardened at room temp.
