Addukte erhältlich durch Umsetzung von cycloaliphatischen oder heterocycloaliphatischen Polyaminen enthaltend mindestens zwei primäre Aminogruppen mit polyfunktionellen Epoxiden mit mehr als zwei Epoxidgruppen pro Molekül in solchen Mengen, dass auf ein Epoxidäquivalent 10-100 Äquivalente Aminwasserstoffatome entfallen,
eignen sich als Härter für Epoxidharz-Klebstoffe, insbesondere für Klebstoffe für Metalle und duroplastische Kunststoffe.
In one embodiment, the present invention relates to a label including: (A) a polymer facestock having an upper surface and a lower surface; and (B) an adhesive layer derived from at least one two-part, high solids curable adhesive overlying the lower surface of the polymer facestock. The present invention further relates to a labeling process, including steps of (A) providing a substrate; (B) coating a two-part curable adhesive to one surface of a polymeric facestock; and (C) applying the adhesive coated surface fo the polymeric facestock to the substrate. The invention also relates to substrates adhered to the label and methods of labeling the substrate. The labels may be applied at ambient or cold temperatures. They can be applied to the substrate even though the substrate has moisture on its surface. The labels adhere to the substrates without the need for externally applied curing means such as radiation.
