Copper foil tape 3M Scotch 1181, 16.5 m × 15 mm, conductive adhesive, ASTM D1000

3M Scotch 1181 copper foil tape, 16.5 m × 15 mm with conductive adhesive, is a self-adhesive copper foil designed for electrical shielding, EMI/RFI grounding, repair and conductivity restoration tasks. The tape conforms to ASTM D1000 and is suitable for use on flat and gently curved surfaces. Its narrow 15 mm width and long 16.5 m roll make it convenient for precision work and repeated repairs in electronics, industrial maintenance and prototyping applications.

Advantages

The copper foil provides reliable electrical conductivity across joints and seams thanks to its conductive adhesive layer, creating effective EMI/RFI shielding and grounding paths. The tape is thin and flexible, allowing good contact on irregular surfaces and easy cutting to length for accurate application. Conformance to ASTM D1000 ensures consistent material properties for industrial and electronics use. The roll format and moderate width make it practical for detailed tasks while minimizing waste.

Suitable for

• EMI/RFI shielding and splicing in electronic enclosures
• Grounding straps and continuity restoration on metal surfaces
• Repairing or restoring conductivity on connectors and contacts
• Prototype assembly, shielding in RF and telecommunications equipment
• General maintenance where thin, conductive tape is required

Key specifications

• Material: copper foil with conductive adhesive
• Roll length: 16.5 meters
• Width: 15 millimetres
• Standard: conforms to ASTM D1000
• Flexible, thin profile suitable for flat and curved surfaces

How to use

Ensure surfaces are clean, dry and free from oil, dust or loose particles before application. Cut the tape to the required length with scissors or a knife, then press the adhesive side firmly onto the target area to establish electrical contact. For best conduction across joins, overlap edges or use additional tape to guarantee continuity. When applying around curves, smooth the tape gradually to avoid air pockets and ensure full adhesion. Trim excess material after application for a neat finish.

Usage recommendations

For reliable shielding and grounding, prepare metal contact points by cleaning with isopropyl alcohol or a suitable solvent. Avoid stretching the tape excessively during application to prevent wrinkles that can reduce conductive contact. In high-humidity or outdoor environments, consider additional mechanical fastening or protective overwrap to maintain long-term performance.
