Urea-formaldehyde (UF), also known as urea-methanal, so named for its common synthesis pathway and overall structure, [1] is a nontransparent thermosetting resin or polymer. It is produced from urea and formaldehyde. These resins are used in adhesives, plywood, particle board, medium-density fibreboard (MDF), and molded objects.
Urea Formaldehyde Concentrate (UFC) – The development of Urea Formaldehyde Concentrate (UFC) was patented by TogliattiAzot in 1998. [33] The company produces two grades of UFC: a processing granular nitrogen, and a resin base at the company's factory at Sheksninsky.
Furthermore, some manufacturers used excess formaldehyde to ensure chemical bonding of all of the urea. Any leftover formaldehyde would escape after the mixing. Most states outlawed it in the early 1980s after dangers to building occupants were discovered. However emissions are highest when the urea-formaldehyde is new and decrease over time ...
