UREA-FORMALDEHYDE RESINS

Urea-formaldehyde (UF) resins have assumed a special position among the aminoplastics on account of their economic importance. Most of the UF resins produced throughout the world are used for making wood adhesives for the production of wood chipboard, polywood and furniture. Regulations to reduce environmental pollution and orders by building authorities to reduce formaldehyde emission from chipboard, plywood etc. , have led to new resins and improved formulations. Recent developments also in the field wood-based products are opening up new applications for UF resins. Other interesting fields where urea resins are being used the textile and paper industries, in the production of foam resins and surface coatings, for which modified urea resins are mainly used.
