The use of load-bearing adhesive joints in the glass structures have been in the focus of research throughout the last years. Due to design aspects, the transparent adhesives are of particular interest. This article – based on a concluded PhD-theses – focuses on the group of two-component epoxy adhesive. These group of adhesives have hardly been taken into account in the glass technology sector up to now. Overall, eight epoxy resin adhesives were shortlisted, and thoroughly characterized. The executed investigations are divided into the recherche of suitable epoxy resin adhesives, the characterization of the adhesives, as well the analysis of the adhesive joint. Within the investigation program, great emphasis was placed on a balanced weighting of different criteria. This article provides an overview about the extensive studies to the characteristics and to the behaviour of transparent epoxy resins.
