Abstract
An electroconductive coating composition which function as a sealer/primer includes (a) a radiation curable, polymerizable compound, (b) a photoinitiator and (c) a conductive pigment. The conductive pigment may be a mixture of pigment including a blend of conductive pigments as well as conductive pigment. Conductivity enhancers may, also, be added. The polymerizable compound is, preferably, a U curable acrylate functional compound which may be monofunctional or polyfunctional. The composition is particularly useful for sealing and priming SMC panels.
