Structural Epoxy Adhesive
7440 is a black, toughened, pasty epoxy resin adhesive for application with composite or metal parts. The resin provides excellent strength build up after a long pot life, very good heat resistance as well as remarkable mechanical properties over a broad temperature range. 7440 is characterised by easy processing, despite high paste stability.
