Epoxies are used to install and fasten sensors, while providing thermal contact and electrical insulation, with the sample. Epoxy can also be used for mechanical attachment and joints. Stycast® 2850FT is a black epoxy resin, and has a thermal expansion coefficient that is matched to copper. A silver-filled, low-temperature conducting epoxy provides excellent strength, along with electrical and thermal conductivity.
This epoxy is used to permanently attach test samples or temperature sensors to sample holders. It is a 100% solid, two component, low temperature curing, silver-filled epoxy which features very high electrical and thermal conductivity combined with excellent strength and adhesive properties.
|ESF-2-5||Low temperature conductive epoxy, 5 packets, 2 g each|
|ESF-2-10||Low temperature conductive epoxy, 10 packets, 2 g each|
- Excellent low temperature thermal and electrical conductivity
- Low viscosity
- No resin bleed during curing
- Low weight loss
- Low volatility
Note: Epoxy must be cured at a minimum of 50 °C for 12 h to achieve proper electrical and physical properties. Curing at 175 °C for 45 s will achieve optimum properties.
ESF-2-5 and ESF-2-10 can be used to 300 mK and below. Results may vary based on application and materials used.
Stycast® is the most commonly used, highly versatile, nonconductive epoxy resin system for cryogenic use. The primary use for Stycast® is for vacuum feedthroughs or permanent thermal anchors. Lake Shore uses this product in vacuum tight lead-throughs with excellent thermal cycle reliability. Stycast® is an alternative to Apiezon® N grease when permanent sensor mounting is desired. (Can place stress on sensor — more information.)
