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.

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.
Fevicol is marketed as a white adhesive, described in company literature as a poly-synthetic resin.It is manufactured through the synthesis of formaldehyde and urea. [4]The product line includes various formulations designed for specific attributes such as bonding strength, impact resistance, curing time, sag resistance, shrinkage, versatility, fire resistance, shock and vibration resistance ...
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 ...

Methylene ureas, e.g. methylene diurea, were commercialized in the 1960s and 1970s, having 25% and 60% of the nitrogen as cold-water-insoluble, and unreacted urea nitrogen in the range of 15% to 30%. In the 1960s in the U.S., the Tennessee Valley Authority National Fertilizer Development Center began developing sulfur-coated urea.
