Conductive Mask & Peel Tape (CMP)

Shield enclosures safely and efficiently

Schlegel Electronics Materials’ (SEM) Conductive Mask Peel (CMP) tape simplifies the manufacture of painted enclosures. CMP is constructed of impenetrable, heat-release mask, highly conductive copper nickel fabric and strong high-tack, conductive adhesive, which secures the tape to the metal for superior EMI shielding. The tape employs Press, Paint, and Peel application and provides total coverage. The CMP tape’s volume resistance is in the range of 0.8 ? cm [average]. When CMP is used with SEM’s EMI shielding gaskets, a highly conductive pathway is obtained, and provides excellent galvanic capability between mating surfaces. Typical applications include large cabinets, factory automation equipment and data storage units.

Press, paint and Peel application is simple, safe, and secure. The operator removes the release liner from the back of the fabric tape and applies it to the prepared bare metal surface. No sharp edges exist that could lead to injuries. The 1-mil polyamide mask prevents infiltration of paint during the spraying or powder-coat process. Enclosures with CMP can be baked at temperatures up to 180ºC (356ºF) for up to 30 minutes. The low-tack mask releases during baking to reveal the highly conductive fabric surface and can be easily removed.
