Urea-formaldehyde resins ingredients used

The principal end use of urea is to provide combined nitrogen for solid fertilizer formulations. Some urea is also converted to biuret (H2NCONHCONH2, also called carbamoyl urea) and to a sulfur derivative, which are sold as Kedlor [65] and Urasil [66] cattle feed supplements, respectively. Urea is also used to a lesser extent in the manufacture of plastics components, such as melamine, and as a component of urea-formaldehyde resins used as adhesives. It is also used as a component of foam-in-place formulations as a rigid insulating material [67], and as an ingredient in noncorrosive aircraft deicing solutions [67a].
