Main features
- Typical Z-axis electrical resistance`
- Typical expected shielding effectiveness is 40-60 dB
- Ten thicknesses from 130 to 500 µm
Product Description
3M-9793KT is an XYZ-axis electrically conductive double-sided pressure-sensitive adhesive tape that combines conductive acrylic PSA with a porous conductive foam matrix. The tape creates an adhesive electrical path between joined substrates and is used in grounding and EMI shielding in equipment and electronic components. Ten thickness variants from 130 to 500 µm provide options for different assembly geometries, with a transparent PET release liner supplied for handling before application. Product selection should consider thickness, adhesion target, surface condition and the pressure needed to develop sufficient adhesive contact and electrical connection.
Key features
- XYZ-axis conductive construction: Conductive acrylic PSA and a porous conductive foam matrix form the electrically conductive tape structure.
- Z-axis electrical resistance: 0.01-0.25 Ω under 3M ETM-12 test conditions.
- EMI shielding performance: Typical expected shielding effectiveness of 40-60 dB through the tape thickness using standard EMI shielding test methods.
- Thickness range: Ten variants from 130 to 500 µm support different assembly geometries.
- Adhesion to stainless steel: Face- and back-side target values range from 1000 to 2500 gf/inch by thickness under ASTM D1000.
Applications / Suitable for
- Grounding between conductive substrates.
- EMI shielding in equipment.
- Conductive pressure-sensitive attachment in electronic components.

Adhesion values are target/typical data measured to stainless steel in accordance with ASTM D1000 and are not specification limits.
Application and bonding process
Bond strength depends on adhesive-to-surface contact, substrate type and surface condition. Firm pressure after assembly is also used to develop wet-out and engage the conductive adhesive with the substrates to establish electrical connection. Pressure, dwell time and moderate heat are process variables to evaluate for the specific assembly.
Firm pressure after assembly develops adhesive contact and engages the conductive adhesive with the substrates.
Shelf life is 12 months from the date of manufacture when the tape is stored in roll form, in its original packaging, at 10-25°C (50-77°F) and less than 60% relative humidity. After removal from the original packaging, converted, shipped and stored material should remain within the prescribed temperature and humidity controls. If the release liner is exchanged during converting, test the replacement liner with the tape; transferred release agents can reduce tack, adhesion, electrical performance and shelf life.
Electrical and EMI performance
Values shown are representative/typical and are not specification limits. Electrical resistance and shielding performance depend on contact and test conditions.
| Property | Value | Unit | Method / condition |
|---|---|---|---|
| Z-axis electrical resistance | 0.01-0.25 | Ω | 3M ETM-12; 10 mm x 10 mm contact area, one pass with a 2 kg rubber roller, 20-minute dwell, then DC resistance measurement. |
| Shielding effectiveness | 40-60 | dB | Typical expected range through the tape thickness using standard EMI shielding test methods. Result depends on conductive-layer construction, adhesive contact, surface smoothness and test frequency. |
