UV-curing acrylate adhesives are considered as promising for use in adhesively bonded joints for structural glass design, not least because of their transparency. Depending on their composition the mechanical properties of these adhesives vary from very soft and flexible to extremely hard and brittle. Nevertheless, there is still no product that is widely used in glass construction. Within this paper, various UV-curing acrylate adhesives covering the whole bandwidth of achievable material stiffness are investigated by means of DMTA and uniaxial tension tests. The obtained material properties as a function of time and temperature, and with respect to tensile strength, are used to characterize potential fields of application in structural glass engineering. Against this background, a comparison is made with the state-of-the-art method of Structural Silicone Glazing regarding the application process and design procedure.

Dominik Offereins M.Sc. (27 Years old) reached his Bachelor’s Degree at the Technical University of Applied Sciences Regensburg in 2018. He then continued his studies at the Technical University Munich focusing on Structural Engineering and graduated with a Master’s Degree in 2021. Since July 2021 he has been working at the University of the Bundeswehr Munich under the supervision of Univ.-Prof. Dr.-Ing. Geralt Siebert. His research now focuses on structural adhesives for glass-to-steel connections with special attention to the material behaviour after ageing and under high temperatures.
