Hot melt adhesive bonding objects will be stronger after pressing

2021/03/09

       When using hot melt adhesive to bond objects, applying a certain pressure on the bonded objects after bonding can often make the bonding stronger.

       The reason is that applying a certain pressure can promote the plastic flow of the hot melt adhesive, which is conducive to the uniform spread of the hot melt adhesive on the surface of the adherend, and the hot melt adhesive can be fully filled into the surface defects of the adherend, thereby increasing the bonding area.

       Based on this principle, applying a certain pressure after the hot melt adhesive is bonded to the object can increase the bonding strength.
