Bonding Processes in Automotive Manufacture

Five bonding processes used in the automotive industry, ranging from structural adhesive to nonstructural and filler, are discussed in this paper. Surface preparation, including use of primers; nature, application, and curing of adhesive; secondary processes; in-line testing and destructive test methods; and repair processes are covered. The integral bonding of disc pad shoe assemblies is detailed. Vinyl plastisol adhesives are used for bonding assemblies. Windshield and backlight bonding is a semistructural adhesive application. Contact bonding cements bond exterior vinyl roof covering to roof panels. A vinyl plastisol sealer replaces solder on the joint between the roof and rear quarter panel.
