ABSTRACT:
Disclosed is a binder composition for binding substrates such as wood furnish for particleboard manufacture. The binder comprises a mixture of a first aqueous solution, comprising a buffering salt catalyst and preferably an acid, with a second aqueous solution comprising urea and formaldehyde. Methods of using the buffering salts as catalyst for curing urea-formaldehyde resins are also disclosed.
