EMI/RFI Shielding

Conductive coatings are functional coatings that are intended for EMI/RFI (Electromagnetic Interference/Radio Frequency Interference) shielding and other applications which require electrical conductivity. They are also used for electrostatic discharge where static grounding is needed. These coatings are generally applied to plastic parts, used in the computer, electronic, and medical fields. The coating is usually applied to the inside surfaces of an enclosure creating a Faraday's cage once the product has been assembled. Copper and silver coated conductive paints are applied with specialized agitated paint spraying equipment. The purpose for the coatings may be for passing UL or FCC requirements, to get the product to market and to meet customer specifications regarding EMI/RFI attenuation.
