Henkel Loctite STYCAST 2850GT Black, formerly Emerson and Cuming, is a two component, room temperature curing, epoxy encapsulant that is used for components that are exposed to thermal shock and need heat dissipation. It contains fillers that are hard and gritty. It offers a low coefficient of thermal expansion, electrical insulative and thermally conductive properties. 1 gal Pail.
Typical Use: | Used for the encapsulation of components which need heat dissipation and thermal shock properties. |
