Abstract
A shielded plastic enclosure for housing electronic equipment is provided, on at least one interior surface thereof, with a layer of shielding composition which is a suspension of silver-coated magnetite particles in a U.V. cured cycloaliphatic epoxy resin. The layer of this shielding composition has a thickness sufficient to effectively shield against electromagnetic interference, radio frequency interference and electrostatic discharge.
Claims3
A shielded plastic enclosure for housing electronic equipment having at least one interior surface of said enclosure provided was a layer of a shielding composition comprising a layer of a suspension of silver-coated magnetite particles in a U.V. cured cycloaliphatic epoxy resin, wherein said shielding composition contains by volume 25 to 75 percent silver-coated magnetite spheres based on the total volume of said shielding composition, said layer having a thickness sufficient to effectively shield against electromagnetic interference, radio frequency interference or electrostatic discharge, said shielding composition having been cured by exposure to a U.V. source having an output in the region between 360 nm and 420 nm for a time sufficient to cure said cycloaliphatic epoxy resin.
