Highly branched polymer PAMAMs (HPBs) becomes a new kind thermosetting adhesive and related adhesion promoter, interfacial adhesion and durability have been significantly increased (100-250%) after modifying, while at lower concentrations it can effect best, it has wide applications and can be used as a binder for variety of plastic and metal.
