Reasons for the drying of solvent adhesives:

1, is mainly a heat from the air to the adhesive layer and the solvent from the inside of the adhesive layer to the surface, after the surface gasification and diffusion to the air transfer process.

2,During the entire drying process, the drying speed, that is, the volatilisation speed of the solvent, changes.

3, Once the adhesive is coated, the solvent will evaporate quickly before entering the dryer oven. Due to volatilization and heat absorption, the surface temperature of the adhesive layer will decrease and the volatilization speed will decrease.
