CuPro-CoteTM Conductive Paint

CuPro-CoteTM is a sprayable metallic coating system using a specially formulated non-oxidizing copper as the conductive agent. Developed for use an as RFI and EMI shield for plastic electronic equipment housings, it can be used on acrylic, ABS and structural foams (such as Noryl, Valox, etc) as well as solvent sensitive substrates such as polycarbonate and polystyrene.

Application notes:

Because this is a latex paint, it is non-toxic, non-flammable, and non-hazardous. Clean-up is simple with warm soapy water. Dry coating is soluble in basic solution. To improve abrasion resistance, paint over with ordinary latex paint after completely dry, in any desired color. For outdoor applications, you must paint over with exterior grade latex paint. Use ordinary latex primer when indicated.

Proper grounding improves shielding effectiveness. One simple way to ground the paint is to coat a suitable area and allow to dry, then attach a properly grounded metalized tape with conductive adhesive in an inconspicuous area such as along a corner of the room or enclosure. Then simply paint right over the conductive tape, making good paint contact between the painted surface and conductive tape. Thicker application does not necessarily provide better performance as copper particles may settle during drying.
