The conductive coating’s primary application is to ground working surfaces to avoid static, but can also act as electric contact paint or carbon shielding paint in low-frequency RFI shielding applications. You can also use the 838AR 340G for shielding metal detectors and other devices where a metal-filled conductive paint would cause malfunction. 

Thermally Conductive Epoxy Encapsulating and Potting Compound - MG Chemicals 832TV-450M

Another customer favorite is MG Chemical’s 832TV-450ML, a thermally conductive epoxy and potting compound with exceptional chemical and water resistance to brine, acids, bases, and aliphatic hydrocarbons. The 832TV-450ML comes with two bottles, labeled Part A and Part B, with an easy 1:1 ratio for mixing.
