Overview of EP62-1HT
EP62-1HT is a two-component epoxy system known for its resistance to aggressive chemicals, including cyclohexane, and is used in demanding applications such as aerospace and electronics. It offers a long working life and versatile curing schedules, making it suitable for bonding optical components like borosilicate glass.

Application
The epoxy was used in a Stanford University study to bond components of a vessel designed to investigate chemical reactions accelerated by electric fields. The vessel housed a cyclohexane solution of cis-stilbene, irradiated with IR and UV light. EP62-1HT ensured the adhesion of critical components in the presence of cyclohexane.

Key Parameters
The vessel design required compatibility with chemicals and laser wavelengths. The optimal design included borosilicate glass tubes and an aluminum-housed pinhole, secured with EP62-1HT and EP41S-5. The epoxy's resistance to acids and solvents was crucial for maintaining component integrity.

Results
The study demonstrated that a nonresonant IR field increased the reaction yield of cis-stilbene photoisomerization. Despite some pinhole damage over time, EP62-1HT maintained the adhesion of the pinhole to the glass tubes, ensuring effective overlap of UV and IR light.
