Urea-Formaldehyde-Precondensate (UFC)

Urea-Formaldehyde-Precondensate (UFC) is a low molecular poly-condensation product of Urea and Formaldehyde dissolved in water, which is used in the glue and resin industry as a pre-product of glues for the manufacture of particle boards, or as anti caking additive for Urea production. The Meissner process for UFC production works with direct absorption of the gaseous Formaldehyde, which is generated by the Metal Oxide Catalyst process for Formaldehyde, in aqueous Urea solution. The obtained solution shows a very high Urea-Formaldehyde concentration of up to 85 %, which allows that down stream glue plants can do without any distillation unit for the otherwise necessary water removal. Likewise to the production of Formaldehyde itself with the Metal Oxide Catalyst process, the waste heat of the Formaldehyde reaction section is used for steam generation.
