The document describes the features and characteristics of 3M 1182 tape, which consists of a 1-ounce deadsoft copper foil backing coated on both sides with a conductive pressure-sensitive acrylic adhesive. The tape is used to bond two surfaces together, both electrically and physically, and is commonly used in EMI shielding solutions for electronic enclosures.
3M 1182 tape consists of a 1‑ounce dead‑soft copper foil backing coated on both sides with a pressure‑sensitive conductive acrylic adhesive. It is supplied with removable liners for easy handling and die‑cutting, and is offered in standard widths from 1/4" to 23" with a standard length of 18 yards (longer lengths available on request).\n\nKey properties include a backing thickness of 11.4 mil, total thickness of 33.5 mil, breaking strength of 1.25 lb/in, adhesion to steel of 1.35 oz/in, and an electrical resistance through the adhesive of about 0.010 Ω over a 1 in² area. The tape meets UL‑510 flame‑retardancy requirements.
| Backing thickness | 11.4 mil (0.04 mm) |
|---|---|
| Total thickness (backing + adhesive) | 33.5 mil (0.088 mm) |
| Breaking strength | 1.25 lb/in (44 N/10 mm) |
| Adhesion to steel | 1.35 oz/in (3.8 N/10 mm) |
| Electrical resistance through adhesive | 0.010 Ω (few milliohms per in²) |
| Flame retardancy | Pass (UL‑510) |
The resistance of the conductive path through the adhesive typically measures only a few milliohms, about 0.010 Ω over a 1 in² area.
