Urea formaldehyde (UF) Powder Resin

The product is a water-soluble urea-formaldehyde powder resin for plywood gluing.The powder resin is also suitable for particleboard manufacturing and wood gluing in cold-pressing applications.

They convince by their high reactivity and good performance in the production and by their low price, however they lack in water resistance of the hardened resin owing to the reversibility of the aminomethylene link and hence the susceptibility to hydrolysis. This need can be overcome by introducing other components like melamine to the UF resin molecules.
