Abstract:
    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 comprising a water soluble amylaceous hydrolyzate with a heterocyclic compound comprising the reaction product of glyoxal, urea, and formaldehyde, alone, or in further combination with ethylene glycol, with a solvent, and with an acid effective to control the rate of cross-linking between said polyol and said heterocyclic compound; forming the admixture in a shape and curing the shape to a bonded article.
