Bonding Hardware—Increased fastener interface and hardware load capability—maximum strength

   

General Bonding–Join parts with epoxy thickened to create a structural gap filler—strength/gap filling

 

Bonding with Fillets–Increase joint bonding area and create a structural brace between parts—smoothness/strength

 

Laminating–Bond layers of wood strips, veneers, planks, sheets and cores—gap filling/strength

 

Fairing–Fill low areas and voids with an easily shaped and sanded surface filler/fairing compound—sandability/gap filling

Selecting Fillers
As a rule, use higher-density fillers when bonding higher-density materials such as hardwoods and metals. Any of the adhesive fillers are suitable for most bonding situations. Your choice of a filler for general use may be based on the handling characteristics you prefer. Fillers may also be blended to create mixtures with intermediate characteristics.
