- 2 part epoxy 1:1 mixing by volume.
- 50-150 steam autoclave cycles (mode of failure, fracture/peeling)
- Very rigid when cured.
- Initial viscosity � little more than water but less then honey. Can be applied when it thickens a little bit.
- 6 month uncured shelf life (would lest much longer but not certified )
- Setup time 45 minutes.
- Cure at room temperature overnight and then cure with heat.
- To ensure proper mixing heat left over mixture for a few hours at 200 F until solidifies; if it is still tacky then mixing was incorrect.
- Mix slowly, bubbles are bad.
- Humidity is bad.

Epoxy Technology, Inc: EPO-TEK 353ND:
- Adv: Can be purchased in small packets(4grams) from Thorlabs.com ( ~$50/10 packs)
- Inexpensive
- Requires an oven (Dr. Kang's lab has one) or a hair drier
- The epoxy will thicken in 4 hours but as soon as it is heat cured it will run thin. Experiment first.
- If thicker consistency is required leave the mixed epoxy in its bag overnight and then use the heat gun
to soften it so it flows. It will harden with a bit more heat.
