For Plastics 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 5 or 20 litres for larger quantities.

Conductive Silver Coating 3850
Silver Pigmented Conductive Coating
Silver Coating 3850 is the latest in a series of coatings which provide Electromagnetic Compatibility (EMC) and it has been specifically designed to give increased coverage while maintaining a very high conductivity. Thus it is a very economic means of achieving excellent shielding against radiated electromagnetic interference (EMI).
It maintains its low resistance even after exposure to heat, cold, humidity and salt spray. It is an air drying system that requires no primer or top coat. It is easily applied by spray or brush and is compatible with plastics commonly used for electronic equipment enclosures.
For higher demands and larger quantities we can sputter a full metal coating on 90% of commonly used plastics, even on PTFE! Normally this is done with a sandwich of three thin layers of metal. First a thin layer of stainless steel, to prevent the softeners in the plastic affecting the shielding. Then a thin layer of copper for superb shielding performance and finally a second layer of stainless steel to avoid corrosion.
