Koperafschermband 3M Scotch 1245, 16,5 m × 25 mm, geleidende koperfolietape

Copper shielding tape 3M Scotch 1245, 16.5 m × 25 mm, conductive copper foil tape is a thin, flexible conductive copper foil tape with an adhesive backing designed for electrical shielding, EMI/RFI suppression, grounding and repair tasks. The tape's conductive copper surface and pressure-sensitive adhesive provide a low-resistance path for stray currents and electromagnetic interference control in electronic assemblies, cable wraps, enclosures and HVAC systems. The roll format and 25 mm width allow easy handling and precise application in confined or detailed work areas.

Advantages

The tape combines a conductive copper foil layer with a conductive adhesive to ensure electrical continuity across overlaps and joints, delivering consistent shielding performance without the need for additional soldering. Its thin, conformable construction enables it to follow curved surfaces and irregular profiles while maintaining contact. The adhesive backing adheres reliably to common materials used in electronics and enclosures, and the roll length provides sufficient material for multiple repair or shielding operations.

Suitable for

• EMI/RFI shielding in small electronic enclosures and chassis
• Grounding straps and continuity repairs for cable shields
• Sealing and repairing HVAC sensor and control housings
• Shielding around connectors, seams and joints in assemblies
• Prototype work, lab repairs and field service maintenance

Key specifications

• Material: conductive copper foil with conductive adhesive
• Length: 16.5 m
• Width: 25 mm
• Form: pressure-sensitive adhesive tape on a roll
• Surface: metallic copper finish, thin and conformable
• Intended use environment: indoor, electronics and enclosure applications

How to use

Clean and dry the substrate surface to remove oils, dust and loose particles before applying the tape. Measure and cut the required length, then press the tape firmly onto the surface, smoothing out wrinkles to ensure continuous contact. For overlaps or joints, apply slight pressure along the seam to promote conductive adhesion through the overlap. When attaching to a grounding point, ensure an appropriate conductive path to the chassis or earth connection is established and verify continuity with suitable test equipment.

Recommendations

Store rolls in a cool, dry place away from direct sunlight and humidity. Use the tape on compatible clean surfaces for best electrical contact and peel strength. Avoid prolonged outdoor exposure or immersion; this product is intended for indoor use and precision shielding tasks. For critical grounding or long-term outdoor installations consider additional protection or alternative materials designed for harsh environments.
