description Disclosed herein is a method of manufacturing a bonded particulate article by admixing particulate material with a binder system, the binder system being formed by admixing a polyol selected from the group comprising a saccharide, a saccharide polymer, and a glyco protein with a heterocyclic compound of the formulawherein R1 and R2 are, independently, aryl of from 6 to 12 carbon atoms, alkyl of from 1 to 6 carbon atoms or substituted alkyl of from 1 to 6 carbon atoms wherein the substituting group is hydroxy, alkoxy of from 1 to 6 carbon atoms, hydroxyalkoxy of from 1 to 6 carbon atoms, cyano, carboxy, carbalkoxy of from 1 to 7 carbon atoms or carbamoyl, or when R1 is -CxH2x-, R2 is -CxH2xO-, x being from 1 to 6, X is oxygen, sulfur or imino and Z is a divalent bridging radical, with a solvent, and an acid effective to control the rate of crosslinking between said polyol and said heterocyclic compound; forming the admixture in a shape; and curing to form the bonded article.
