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.
Arkema S.A. is a publicly listed, multi-national manufacturer of specialty materials, headquartered in Colombes, near Paris, France. It has three specialty materials segments (or divisions); adhesives, advanced materials and coatings. A further segment covers chemical intermediates. [2]
Sensitization to formaldehyde has been decreasing since 1980 due in part to the replacement of formaldehyde by these formaldehyde releasers. [2] As of 2009, frequency of sensitization to formaldehyde is stable at 2–3% in Europe. [2] It might be as high as 9% in the USA. [2] [13]
Solenis' line of Soyad adhesives contains no formaldehyde and low volatile organic compounds (VOCs). Typical interior wood products include urea formaldehyde (UF) in their adhesives. Over time, UF releases free formaldehyde into the air in a carcinogenic gaseous form, which can be inhaled by humans.
Some people have a contact allergy to imidazolidinyl urea causing dermatitis. [3] Such people are often also allergic to diazolidinyl urea. In addition to being an allergen, it is a formaldehyde releaser, since it generates formaldehyde slowly as it degrades. Although the formaldehyde acts as a bactericidal preservative, it is a known carcinogen.

The result was Aerolite, a urea-formaldehyde adhesive which unlike conventional glues of the time, resisted water and micro-organisms. Further research showed that gap-bridging hardeners incorporating formic acid enabled Aerolite to be used as an assembly adhesive. Aerolite was the first adhesive of its type to be invented and manufactured in ...
