Abstract
Two-component systems are described which are suitable for underlining, adhesive bonding of the crimped fold and sealing of auto body sections, particularly for crimped fold sealing of add-on vehicle parts. The two-component systems attain the requisite grip strength for mounting the add-on parts on the body as well as the requisite strength and dimensional stability for the production process up to and with the CIP passage, within the predetermined cycle time, on the basis of cross-linking of the sealant composition twice. In one embodiment, the surface of the two-component system is pre-cross-linked by a UV-induced reaction and by the cross-linking of the two-component system to the extent of portability. In addition, two-component systems are described which cross-link intentionally only partially up to a consistency that permits a rugged course of the process through cleaning baths and which harden completely only by means of a further hardening process, for instance in the CIP forced circulation oven.
