Phenolic Resin also called Rosin Modified Phenolic Resin, it's a type of polymer material that made from gum rosin with condensation reaction of phenols & aldehydes, features with thermostability, high mechanical strength, acid resistance, rub resistance and electric insulativity. In the application for adhesive, phenolic resin can greatly improve adhesive strength and thermostability, its bonding strength can be remained under 300°C, very suitable for bonding processes of composite wood and composite plastic manufacturing, it also comes with water-resistance.
