3M Electrical Tape, 25mm Width, 10m Length - 7100313410


This electrical tape is a thin copper foil tape coated with an acrylic adhesive, designed for electrical and electronic work where conductive shielding and insulation are required. It is supplied in a gold finish and intended for use in environments that demand a compact, conformable conductive layer for tasks such as shielding, earthing and precision repairs.

Features & Benefits


• +121°C maximum operating temperature enables high-temperature use
• -40°C minimum operating temperature supports low-temperature stability
• 0.023mm thickness delivers minimal profile for tight assemblies
• Acrylic adhesive provides consistent adhesion across substrates
• Copper foil backing offers conductive EMI shielding and earthing

**Applications**


• Suitable for EMI/RFI shielding on circuit boards and enclosures
• Ideal for repairing conductive traces and earth paths on PCBs
• Used with cable harnesses to provide local shielding and continuity
• Can be used for bonding conductive pads in automation equipment
• Suitable for edge-wrapping and seam sealing in electronic assemblies

How is electrical continuity achieved when applied?


The metal backing provides a conductive path across contacted surfaces while the adhesive ensures intimate contact to maintain electrical connection.

What form factor and coverage does it provide for small repairs?


It is supplied as a 25mm-wide roll with 10m length, allowing precise cuts for spot repairs and extended runs without excess overlap.

How does the tape behave under temperature cycling?


The acrylic bond retains adhesion across a wide thermal range, maintaining contact from -40°C up to +121°C without significant loss of adhesion.

Is the tape suitable for use in regulated electronics assemblies?


Its RoHS compliance indicates the materials meet common restricted-substance criteria for electronics manufacturing.

What practical advantage does the gold finish offer?


The plated appearance helps visually identify conductive areas and eases inspection in assembly and repair tasks.
