Henkel Loctite STYCAST 2850MT Black, formerly Emerson and Cuming, is a two component, room temperature curing, epoxy encapsulant that is used for encapsulating components that are exposed to thermal shock, high voltage applications, and those that need heat dissipation. It has a low coefficient of thermal expansion, low viscosity, good thermal conductivity, impact resistance, and excellent electrical insulative properties. It contains a filler that has a grainy consistency. 1 gal Pail.
