An organometallic composition, suitable for use in curing polyisocyanate compositions, comprises a complex of at least one metal selected from iron, cobalt and aluminium and at least one beta-dicarbonyl compound wherein when the metal is iron (II) or cobalt (II) the molar ration of beta-dicarbonyl compound to metal is in the range from 2.1:1 to 10:1, and when the metal is aluminium (III), iron (III) or cobalt (III) the molar ration of beta-dicarbonyl compound to metal is in the range from 3.1:1 to 10:1. A polyisocyanate composition containing the claimed organometallic composition and a process for binding lignocellulosic material is also described and claimed.
