A fast and easy way to shield plastic enclosures is by using a conductive paint containing nickel, copper or silver. The paint comes in aerosols for easy use, but can also be supplied in tins of 7 kg (3805) and 28 kg (3820) for larger quantities.
The nickel conductive coating contained in an air-drying acrylic resin. The resin becomes touch dry 15 minutes after application and achieves maximum conductivity within 24 hours. It is intended to prevent electrical interference, penetrating enclosures fabricated from thermoplastics and other insulating materials. The coating will also prevent static build up.
It is recommended that an earth connection is made to achieve maximum shielding performance. A suitable material is copper shielding foil 3201 which may simply be pressed on or oversprayed. The applied coating has a matt grey textured finish.
Benefits:
Low surface resistivity of 0.9Ω/sq giving a high attenuation
Aerosol enables speed and ease of coverage of complex shapes
