① It serves as the medium for the polymerization reaction, making the reaction milder and the temperature easier to control.
② It dissolves the base material to prepare solvent-based adhesives.
③ It acts as a diluent to dilute the adhesive to a certain viscosity, which is beneficial for wetting and facilitates coating.
④ It regulates the volatilization rate of the adhesive.
⑤ It prevents gelation and is used to increase the storage stability.
⑥ It is used as a surface cleaning treatment agent before bonding.
⑦ It can directly bond certain plastics.
⑧ It reduces costs and improves efficiency.
