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.
2007: Arkema sells its agrochemical business (Cerexagri) to United Phosphorus [12] and its urea-formaldehyde activities to Hexion. [13] 2007: acquires Coatex company (specialty acrylic polymers) 2010: acquires acrylic Dow assets in the US [14] 2011: acquires Total coating resins (Cray Valley and Sartomer) [15]
As a result, Solenis developed a completely formulated soy adhesive for use in wood composites, which offers furniture manufacturers and consumers a safer alternative. Solenis' line of Soyad adhesives contains no formaldehyde and low volatile organic compounds (VOCs). Typical interior wood products include urea formaldehyde (UF) in their ...
The company ventured into the sports floor market with PlybooSport in 2006 with its first installation in Dallas, Texas, where Smith & Fong first launched its flooring business 13 years prior. [1] In 2007, Smith & Fong announced it would be converting its manufacturing operations to run urea formaldehyde-free adhesives (PlybooPure™) on its ...
Controlled-nitrogen-release technologies based on polymers derived from combining urea and formaldehyde were first produced in 1936 and commercialized in 1955. [3] The early product had 60 percent of the total nitrogen cold-water-insoluble, and the unreacted (quick-release) less than 15%.
The basic reaction of urea and formaldehyde to create a urea-formaldehyde resin, followed by the condensation [12] Urea-formaldehyde resins (UF) are a class of impregnation resins for wood modification made by reacting urea with formaldehyde. This resin can be polymerized after impregnation into the wood substrate by oven-curing.

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 ...
