Structural bonding in the bodyshell means that the adhesive assumes functions of stiffness, crash strength and endurance strength, whereby the characteristics of the bodyshell are positively influenced in a significant way.
A high-strength, heat-hardening single-component epoxy resin adhesive, which hardens fully in the cathodic immersion paint drying oven, is used for the conventional steel bodyshell.
In the event of repairs, this adhesive is replaced by a cold-hardening two-component epoxy resin adhesive, since the hardening temperatures necessary for the single-component epoxy resin adhesive cannot be used on an assembled vehicle.
