1194 Copper Foil Tape is a non-conductive tape consisting of a 1-ounce dead soft copper foil backing and an aggressive non-conductive pressure-sensitive acrylic adhesive. It is typically used for applications requiring economical electrical bonding, grounding, and EMI shielding. The copper foil backing is solderable and resists oxidation and discoloration.
The 3M 1194 Tape is a 1‑ounce dead‑soft copper foil backed with an aggressive nonconductive acrylic pressure‑sensitive adhesive. It is supplied on a removable liner for easy handling and die‑cutting, and is available in standard and custom widths from 1/4" to 23" and lengths up to 36 yards or longer on request.
Typical applications include economical electrical bonding, grounding, and EMI shielding. The copper backing is solderable, resists oxidation, and provides shielding effectiveness of about 50 dB to 60 dB (30 MHz‑1 GHz). Technical specifications such as foil thickness, breaking strength, and adhesion are listed on the sheet, along with flame‑retardancy and UL certification information.
