Shielding Tape 3M Scotch 1181, model 118119 — length 16.5 m, width 19 mm

3M Scotch 1181 shielding tape (model 118119) is a conductive adhesive tape with a length of 16.5 m and a width of 19 mm, designed for electromagnetic shielding, grounding and electrical repairs. The tape provides a conductive path and reliable adhesion on compatible surfaces, making it suitable for applications where EMI mitigation and continuity of electrical ground are required. Its conformable backing and pressure-sensitive conductive adhesive allow application around irregular shapes and cables in electronics assembly and repair environments.

Advantages

The tape combines conductive adhesive and a flexible metalized backing to ensure low-resistance contact and effective EMI/RFI shielding. It adheres immediately with pressure-sensitive tack, enabling quick repairs and permanent installations without heat activation. The tape is thin and conformable, permitting use on curved surfaces and in confined spaces while maintaining electrical continuity. Its roll format with 16.5 m length reduces the need for frequent reordering for small- to medium-scale tasks.

How to use

Clean and dry the surface to remove oils, dust and loose particles prior to application to ensure good electrical contact and adhesion. Measure and cut the required length, then press the conductive side firmly onto the substrate, smoothing out creases to maintain continuous contact. For cable shielding, wrap the tape with slight overlap and ensure end connections are electrically bonded to chassis or ground point. Avoid stretching the tape excessively to preserve the integrity of the conductive backing and adhesive.

Usage recommendations

Use on compatible clean, dry surfaces and ensure mechanical fixation or soldered/bonded connections at terminations when long-term low-resistance contact is required. For best EMI performance, maintain overlap and continuous paths to ground. Store rolls in a dry, moderate-temperature environment away from direct sunlight to preserve adhesive properties.
