Title: CHITOSAN-REINFORCED UREA-FORMALDEHYDE ADHESIVES FOR WOOD COMPOSITE MANUFACTURING
Abstract:
It is disclosed chitosan-reinforced urea-formaldehyde (UF) adhesives for bonding wood-based composites, such as plywood and particleboard, or other fibrous materials and the method of producing the adhesives. The adhesives are produced by mixing unmodified chitosan containing raw material and a urea-formaldehyde resin to produce wood composite adhesive resins.
