Urea formaldehyde-based adhesives (UF) are thermosetting resins formed by the polycondensation of urea and formaldehyde. There are two main categories:
Pure urea, both liquid and powder. The gluing process occurs through the use of a hardener which accelerates the reaction and the pressing with a heat press or high frequency.
Self-hardening urea, only in powder, which already contain catalysts and excipients.
They have good heat resistance but do not resist water very well.
On top of being distributors of urea Planarit (Planatol) and Kaurit (Basf), CO.VI.COL. also offers a wide range of own brand UF adhesives.
Wood veneer jointing, flat wood veneer gluing, door production, panel production.
