The following article was printed by Canadian Electronics Magazine. This is forcing manufacturers and hobbyists alike to ensure their devices are properly shielded. Most electronic devices emit electromagnetic radiation in the radio frequency range, and are in turn susceptible to interference from external radio waves.
Electromagnetic radiation is dampened if it passes through a grounded conductor.
These plastic electronic enclosures must be protected with a shielding compound. The easiest way to shield a plastic electronic enclosure is to paint it with conductive coating. Conductive coatings basically consist of a binding agent and a conductive pigment. The properties of the binding agent, or base, will determine the adhesion strength and toughness of the coating. The choice of pigments will determine the conductivity of the coating.
