Novel Method for Cold Bending Glass – Transparent Structural Silicone Adhesive

During a recent project to understand the ability to use Transparent Structural Silicone Adhesive (TSSA) via linear bonding for cable wall fittings, a unique aspect of the material indicates a potential novel method for cold bending glass. Used in long sections and small widths, the TSSA was able to effectively bend and hold shape after processing in an autoclave. The original purpose of the study was to evaluate at what length would the TSSA connection would fail in shear due to a mismatch in coefficient of thermal expansion for the glass and metal. However, the lengths studied indicated a potential to control the amount of bending due to length. The technique presents a potential art to create curved facades in lieu of the use of conventional structural silicone sealants under constant loads. As the TSSA is now the material under constant load, the curved glass could be installed in different façade assemblies via fittings.
