3M 7010349591 Emi Shielding Fabric Tape CN-3190 Acrylic

Product Description

The 3M 7010349591 is an EMI shielding fabric tape, sold as the CN-3190, designed for electromagnetic interference shielding and grounding applications in electrical and electronic work. The tape features a copper nickel-plated fabric carrier with an acrylic adhesive backing and measures 4.3 mils thick. It comes wound on a removable liner that supports die-cutting and clean handling during fabrication or prototyping. The roll spans 20.6 inches wide and 54.5 yards long, making it suitable for covering large surfaces or cutting into custom shapes. Licensed electricians, electronics technicians, and RF shielding specialists are the primary installers of this tape.

This tape is used wherever EMI containment or grounding continuity is required at the component, enclosure, or room level. Common applications include shielding electronic enclosures and chassis, grounding conductive surfaces, and lining shielded rooms or Faraday enclosures. It is also used during electrical prototyping, design validation, and troubleshooting phases where temporary or permanent shielding solutions are needed. The acrylic adhesive and conformable copper nickel fabric allow it to wrap around irregular surfaces without losing contact or adhesion.

Key Features

• Copper nickel-plated fabric carrier provides effective EMI shielding and grounding conductivity
• Acrylic adhesive offers strong, conformable bonding to irregular and flat surfaces
• 4.3 mil total thickness keeps the tape profile low for tight fitment in enclosures
• Removable liner supports precision die-cutting and clean handling during installation
• Suitable for grounding equipment, components, and shielded room construction
• RoHS 2011/65/EU compliant for use in restricted-substance regulated applications

Compatibility

Designed for use in EMI shielding, grounding, and RF containment applications across electronic equipment, component assemblies, and shielded enclosures where a conformable conductive tape with acrylic adhesive is required.

Installation Notes

Installation is typically performed by licensed electricians or electronics technicians working on shielded enclosures or grounded assemblies. De-energize all equipment before applying tape to any conductive or grounded surface. The removable liner should be peeled back progressively to avoid contaminating the adhesive. When die-cutting, use clean tooling to maintain edge integrity and ensure full adhesive contact along cut edges.
