Thermosetting epoxy resin compositions useful as structural reinforcement or structural foam
10767040 · 2020-09-08 · ·

Thermosetting epoxy resin compositions on the one hand at room temperature in the incompletely cured state exhibit extremely slight alteration in shape and on the other hand develop a high surface tack, and, moreover, in the fully cured state are of high impact strength and at the same time exhibits high adhesion, particularly to metallic substrates. These compositions are ideally suited to the production of self-adhesive reinforcing elements.
