Abstract
The bonding of steel locating hinge washers to a hinge assembly to facilitate doors-off/door-on processing through an automotive trim shop. The adhesive bonding system cures during the cathodic electro-cost primer bake cycle. The adhesive maintains an intimate, positive contact with both metal surfaces ensuring adequate bonding performance and maximized bonding surface area during a defined heat or bake cycle.
Claims20
A method of bonding a first metallic object to a second metallic object, comprising the steps of:
- applying a heat-curable adhesive bonding composition to a predetermined percentage of a predetermined metallic surface of said first metallic object;
- bringing said heat-curable adhesive bonding composition applied to said predetermined metallic surface said first metallic object into intimate contact with a predetermined metallic surface of said second metallic object;
- and
- while said intimate contact is maintained, subjecting said applied heat-curable adhesive bonding composition to heat until said adhesive composition cures to bond said predetermined metallic surfaces together.
A method of bonding metal surfaces, comprising the steps of:
- applying an adhesive epoxy film or tape to a first metal surface of a first object;
- said adhesive epoxy film- or tape is capable of withstanding production phosphating solutions, cathodic electro-coat primer solutions, and/or cathodic electroprimer bake temperatures;
- bringing said adhesive epoxy film or tape applied to said first object into intimate contact with a second metal surface of a second object;
- and
- subjecting said first metal surface, said adhesive epoxy film or tape, and said second metal surface to cathodic electro-coat baking until said adhesive epoxy film or tape cures to bond said first and second metal surfaces together.
