Weld bonding adhesive

Weld bond adhesive is used to weld boning application, which is a combination of spot welding and adhesive bonding. Benefit of this method are rigidity increase, improving fatigue property. Weld bonding adhesive is normally applied to one sheet and the joint closed. A spot weld is then made through the adhesive. The electrode force displaces the adhesive to obtain electrical contact between the sheets and a weld is made in the normal way. The adhesive is finally cured at a paint oven to complete the assembly.

Weld bonding adhesive Is based on one component epoxy. It is provided tough physical property, great adhesion strength, long term durability.
