Stycast 2850 FT Range

The Emerson and Cuming - Stycast 2850 FT range is filled to have a low thermal expansion close to that of brass and is the cryogenic epoxy of choice for encapsulation of electrical connectors and vacuum feedthroughs.

Different catalysts are available that offer low viscosity mixes (24LV and 23 LV) for encapsulation, room temperature curing (24LV,23LV and 9) and high temperature operation (Catalyst 27-1 replaces Catalyst 11 which has been retired by the manufacturer). The table below provides a guide to selecting the most appropriate catalyst.
