Why is solvent-based adhesive easy to dry?

by:LINYANG     2019-12-23

solvent-based adhesives are easy to dry for several reasons: 1. It is mainly a heat and mass transfer process in which heat is continuously transmitted from the air to the adhesive layer and the solvent continuously diffuses from the inside of the adhesive layer to the surface, and then diffuses into the air after gasification on the surface. 2. During the whole drying process, the drying speed, that is, the volatilization speed of the solvent, changes. 3. Once the adhesive is coated, the solvent will volatilize quickly before it is put into the oven of the dryer. Due to volatilization and heat absorption, the surface temperature of the adhesive layer will decrease and the volatilization speed will also decrease.
