Eight factors that affect the bonding effect of hot melt adhesive?

       1.Viscosity : Shanghai core - style hot melt adhesive affects fluidity , permeability , spray performance , glue temperature , wire drawing , amount of tapping , etc .
       2 .softening point : influencing glue temperature , heat resistance , curing speed and the like .
       3.Opening time: affects operational applicability, permeability and bonding strength.
       4.Curing speed: affect production speed and bonding strength.
       5.the influence of affinity bond strength.
       6. cohesive force: influence resistance to transfer, peel strength or shear string degree.
       7. Thermal adhesion: affects the bonding effect.
       8. Temperature resistance, etc.: affect the final bonding system can withstand the temperature.
