Parker Chomerics CHO-MASK II HT Conductive Foil Tape
Categories: Polymer; Tape

Material Notes: The CHO-MASK II family of EMI foil tapes includes both Standard Tack (ST) and High Tack (HT) versions for providing a conductive, non-corroding surface on painted metal electronic enclosures. CHO-MASK II tapes consist of recessed polyester paint masking film covering a layer of either 1 oz. (28.4g) or 2 oz. (56.7g) tinplated copper foil. The back of the foil features a conductive pressure sensitive adhesive (PSA). CHO-MASK II tape is applied to clean metal frame, door and panel surfaces where electrical continuity is required. After painting, the peel-off mask is easily removed, allowing the paint to seal both edges of the foil layer. The foil imparts a clean, electrically conductive path from the panel, through an EMI gasket, to the cabinet frame. It also provides grounding points within the enclosure.

Application: Oven bake up to 400°F (204°C) for 1 hour; Suitable for knife edge, radius and flat surface applications; Lengths of <5 ft. above 350°F (177°C) recommended
