Hemming adhesive

An assemble parts such as a hood, a trunk and a door consist of an outer steel panel and inner steel panel. These panels are assembled by swaging so call "Hemming". Hemming adhesive is used in this hemming process in order to increase parts stiffness, rust prevention. Hemming adhesive is based on one component epoxy resin technology. This adhesive is applied at weld shop and then cured at a paint oven. Sunstar’s hemming adhesive features glass bead containing grade. The glass bead containing adhesive gives the hem flange an instant mechanical lock and provides immediate handling strength before curing. Sunstar glass bead adhesive is a cost effective solution that eliminates the need for costly heat induction pre-curing and labor-intensive spot welding.
