The paper reports on the preliminary evaluation of a transparent structural silicone adhesive (TSSA) developed for point fixing in glazing, which combines high transparency, strong adhesion performance, thermal stability, and excellent weatherability. The transparent film adhesive is a heat curing one-part material that shows strong bonding to glass, metals, ceramics, and even plastics typically without primer. The paper presents information on the durability and physical properties of the new material and suggests a methodology for deriving static and dynamic design strength values for the new material based on creep rupture experiments as well as nondestructive dynamic load experiments using the stress whitening phenomenon observed with this material as the limit state. The paper further discusses material characterization and hyperelastic modeling used in the finite element analysis based on finite strain theory.
