Research development of melamine modified urea-formaldehyde resin adhesives

Melamine modified urea-formaldehyde resin adhesives with low free formaldehyde have better water resistance,heat resistance and stability in comparison with urea-formaldehyde resin adhesives. It has been extensively studied in recent years and become an important adhesive in woody industry instead of urea-formaldehyde resin adhesive. The development survey,synthesis mechanism,synthesis technology and applications have been discussed in this paper. The future of research works is also prospected.
