RoHS Protective Conductive Coating for steel

September 16, 2009

Hi,
We have a retrofit application in the field that requires adding an EMI gasket to an existing steel painted metal building. The surfaces that the door gasket adheres to (with conductive tape)and oppositely, seals against; need to be conductive. So in the field, the surfaces have to be stripped to bare metal (the metal is raw CRS) and protected with a durable conductive coating.

I am looking for suggestions for such a coating but it has to be RoHS compliant.

I do have some options like: Spray Zinc or Electro DAG, but am unsure to date of the compliance specifications.

Does anyone have any suggestions ?

Thanks!

Randy
