Abstract
A fabricated tape assembly for 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.
