No, conformal coatings are non-conductive, or insulative. ... To do that properly, a coating must have electrically insulating properties with as high of a dielectric withstand voltage (or strength) as possible.

Is conformal coating thermally conductive?

Thermally conductive epoxy conformal coating is applied between a heat-generating electrical device and a heat sink in order to improve heat dissipation. The coating forms a thermally conductive layer on the substrate, either between components or within a finished product.

Is conformal coating an insulator?

Conformal coatings form a protective, insulating layer. The most common electrical parameter tested is the Surface Insulation Resistance (SIR). This measurement is often taken before and after coating and exposure to harsh conditions, thus ensuring the coating continuously provides the level of insulation required.
