Henkel Loctite STYCAST 2850KT Blue, formerly Emerson and Cuming, is a two component, room temperature curing, epoxy encapsulant that is used for high voltage components and replacing heat sinks. It contains a filler that is gritty. It offers a low coefficient of thermal expansion, reduce stress, and has high thermal conductivity. 1 qt Can.
| Typical Use: | Used for the encapsulation of components which need heat dissipation and thermal shock properties; it is recommended for use in high voltage applications where surface arcing or tracking is a concern. |
