Copper Foil with Conductive Adhesive

3M 1126 is a 3.5 mil, deadsoft copper foil and aggressive electrically conductive acrylic adhesive. Common uses are static charge draining, seaming shielded rooms, cable wrapping, surface contact to non-solderable materials and EMI /RFI shielding. It is typically used for applications requiring excellent electrical conductivity from the application substrate through the adhesive to the foil backing. The copper foil backing is solderable and resists oxidation and discoloration. Many factors determine the true shielding effectiveness of a shielding tape, including type and thickness of foil, adhesive type, intimacy of contact, smoothness of application surface, strength and frequency of the EMI signal, etc.

The physical properties listed are typical values and are not to be considered as specifications. Our suggestions for use are based on tests we believe to be reliable. However, the purchaser must carry out their own tests to determine the suitability of the product for their internal use. Information is given in good faith, but without warranty.

It is essential, as with all pressure-sensitive tapes, that the surface to which the tape is applied be clean, dry and free of grease and oil.

Shelf life from date of manufacture is based on the product being stored at 70°F(21°C) / 50% relative humidity out of direct sunlight.

Specification compliance is dynamic and should only be used as a general guide. Always confirm that the tape you are interested in currently complies with all specification requirements. Please verify that the product number that you select is available in the proper size and color to meet your specification.
