3M 7010302197 Lead Foil Tape 421 Dark Silver 1 in 36 Yd

Product Description

The 3M 7010302197 is a lead foil tape in the 421 series, designed for applications requiring both electrical and thermal conductivity. The malleable lead backing conforms readily to complex shapes, curved surfaces, and detailed patterns, making it well suited to shielding, insulation, and assembly work. The rubber-based adhesive delivers strong, long-lasting adhesion across a wide range of temperatures and surfaces. At 1 inch wide and 36 yards long per roll, this tape ships in a standard roll format and is widely used by HVAC technicians, electricians, and industrial assembly professionals who need a reliable, conductive foil tape.

This tape is used in residential and commercial applications where foil tape must resist flame, moisture, UV degradation, weather exposure, and chemical contact. Common install scenarios include HVAC duct sealing, EMI and RF shielding tasks, radiation shielding in controlled environments, and light-reflective insulation work. The tape can be die-cut into specific shapes or hand-cut to fit detailed configurations on the job or in a manufacturing setting, giving field technicians and fabricators flexibility in how they apply it.

Key Features

• Electrically and thermally conductive lead foil backing
• Highly conformable — can be shaped into complex or detailed patterns
• Resists flame, moisture, weather, UV degradation, and many chemicals
• Heat and light reflective surface for insulation and lighting efficiency applications
• Rubber-based adhesive provides strong adhesion and long service life across a wide temperature range
• Compatible with die-cutting for precision assembly and manufacturing processes

Compatibility

Designed as an OEM-style foil tape replacement and general-purpose conductive tape for HVAC, electrical shielding, and industrial assembly applications where a conformable, lead-foil-backed tape is required.

Installation Notes

Installation is typically performed by licensed HVAC technicians or electricians, depending on the application. De-energize any electrical components before applying this tape in shielding or grounding contexts. Ensure the substrate is clean, dry, and free of oils or loose material before applying for best adhesion. When die-cutting or trimming, use appropriate tooling and handle lead-based materials in accordance with applicable safety and environmental regulations.
