Emulsion adhesive is formed by the emulsification and polymerization of acetic vinyl, EVA and
acrylic resin in water. Since organic solvent is not generally used, it is not flammable, and it is not toxic;
it is a relatively safe adhesive. It is mainly used for porous materials.
- The emulsion adhesive is generally solventless type adhesive that contains no organic solvent agent.
- The emulsion adhesive allows extensive range of work from coating with brush to coating with machine.
- The emulsion adhesive has better initial adhesive property than other aqueous adhesive.
- The emulsion adhesive is relatively inexpensive.

Many types of emulsion adhesives contain less resin solid. Adhesiveness is ensured by "anchoring effect" where
the resin permeates the gap of the adherend to be hardened in the form of wedges. Therefore, insufficient
pressing force will cause defective holes on the adhesion surface and insufficient permeation, resulting
in substantial reduction in the bonding strength. Sufficient consideration must be given to determine the
amount of coating, pressing force and pressing time.
