Copper Foil Tape for Shielding

3M 1194 is a copper foil tape with a non-conductive acrylic adhesive on one side. The roll measures one inch wide by six yards long and carries a 600 V voltage rating. It provides 50 dB of shielding effectiveness and operates up to 150 degrees Fahrenheit. A release liner is included for easy handling.

Suits EMI shielding and grounding tasks

This tape suits technicians who need a flexible copper shield for cables, enclosures or board-level repairs. The single-sided adhesive bonds to surfaces while the copper foil maintains electrical continuity across the joint. Buyers who require a conductive adhesive for direct electrical contact between layers should look at a different product. It is also not intended for high-temperature environments beyond the rated limit.

50 dB shielding effectiveness at 600 V

The 50 dB shielding effectiveness at the rated 600 V determines whether this tape meets the attenuation needs of a specific interference problem. If the application demands higher shielding performance or a different voltage class, this roll will not satisfy the requirement. The 2.6 mil thickness and acrylic adhesive define the mechanical profile for the installer.

Questions about this item

What is the maximum operating temperature for the 3M 1194 copper tape?

The tape is rated for a maximum performance temperature of 150 degrees Fahrenheit.

How much heat does the tape generate during continuous electrical use?

As a passive copper foil tape with acrylic adhesive, it generates no heat itself; it simply conducts current or provides shielding up to its 600 V rating.

What surface preparation or existing materials are needed for the adhesive to bond properly?

The single-sided acrylic adhesive bonds to clean, dry surfaces; the included liner protects the adhesive until application. No primer or special substrate is required beyond standard surface cleaning.
