摘要

In this work, the shear strength for glass-glass (water white, low iron glass microscope slides) and aluminum-glass bonds produced using hydroxide catalysis bonding was evaluated. It was determined that the bond strength increased with extended curing times and elevated curing temperatures. The maximum bonding strength for the glass-glass bond was achieved after 4 weeks at room temperature. The same strength was obtained for a curing time of 24 hrs at room temperature followed by 1 hr at 100 deg C. This shear strength level was comparable to the results for a two-component optical cement, although the bonding interface of the optical cement was much thicker. Aluminum-glass bonding was also completed. The strength levels were lower due to the relative non-flatness (approximately 7 μm peak-to-valley) of the aluminum samples.
