Electrically Conductive Paints and Coatings
Electrically conductive coatings for plastic enclosure electromagnetic shielding are growing in popularity as concerns over weight increase for a variety of EMI applications including: military, aerospace, automotive, telecon, medical and semiconductors. Conductive coatings are generally applied by spraying a layer of electrically conductive paint, which is heavily filled with a conductive metal such as: silver, nickel, copper and a variety of coated or specialty powders and flakes.
Resin type form (paints): acrylic, epoxy, polyester and polyurethane.
A comprehensive range of caulks, adhesives, coatings and greases containing conductive particles for all of your shielding and continuous electrical path requirements.

Electrically Conductive Grease
Conductive greases can be used where sliding or movement might occur between two metal parts and grounding or where RF screening is required. Applications include: surface-to-surface particularly metal-to-metal sliding contact areas requiring continuous electrically conductive paths, such as a switch, and silver-nickel filled silicone polymer designed for effective anti-wear of flanges and airframes.
Fillers: Ag (Silver) & Ag/Ni (Silver\Nickel).
Resin type form: Silicone
Frequently Asked Questions
