good wettability to the bonding surface

have good wetting and high bonding strength. It is rich in raw materials, low prices, it has become one of the most promising adhesive. According to the chemical composition of the matrix, the hot melt can be divided into ethylene - vinyl acetate copolymer type (EVA type), polyamide type, polyester type and polyurethane type and so on, the most important of which is EVA type. Hot-melt curing and other types of adhesives, it does not produce cross-linking reaction, do not rely on the evaporation of the glue solvent to achieve the purpose of curing, but only from the heating and melting state through the cooling process naturally restored to solid. Therefore, the bonding effect of the hot melt adhesive is achieved by virtue of its good wettability to the bonding surface in the molten state and the bonding strength in the cooling and solidified state. The hot melt adhesive is a thermoplastic adhesive material used for melting, which becomes solid when cooled and has a certain strength.
