Referred to as hot melt adhesive, it is a mixture of thermoplastic resins. It is all solid and has a certain fluidity at high temperatures. When the surface of the wetted adherend is cooled, it becomes solid and becomes gummy. Fast adhesive, low energy consumption, no solvent pollution. Used in veneer production for veneer splicing, hole filling or partial wood panel sealing. The main components of hot melt adhesives are polymeric resins, tackifiers, extenders, plasticizers, fillers and antioxidants. The hot melt adhesive for woodworking is mainly ethylene-vinyl acetate copolymer, followed by polyamide or polyethylene. Hot melt adhesives have poor heat resistance and are not resistant to oils and organic solvents, and their properties and equipment used need to be improved.
