Abstract
A method of sealing body parts such as an edge fold of a motor vehicle component, for example a door, a rear or front flap or a sliding roof panel, includes a two-step pre-cross-linking of the sealing composition in the rough body part. In a first step the surface of a UV-active sealing composition is pre-cross-linked by UV irradiation, and in a second step immediately following, the edge fold adhesive and the sealing composition are hardened by thermal action. The edge-sealed body parts produced by the method are transportable and are of visually and functionally satisfactory quality after passing through cleaning baths and after thermal hardening in a KTL kiln. Since the sealing is carried out in the rough body part rather than during the coating process, the method provides a substantial potential cost saving.
