Urea formaldehyde is a type of thermosetting resin that is produced by the reaction of urea and formaldehyde. This resin is commonly used in the production of adhesives, particularly for wood products such as particleboard, medium-density fiberboard (MDF), and plywood. The resin provides excellent bonding properties and is valued for its water resistance and durability. Urea Formaldehyde Concentrate (UFC 85) is a clear and viscous liquid, composed of formaldehyde, urea and water. It provides high concentration of formaldehyde commercially available in an easy-to-use form.
