3M 7000029006 Lead Foil Tape 420 Silver 0.8 in X 36 Yd

Product Description

The 3M 7000029006 is a lead foil tape with a rubber-based adhesive, sold under the 3M 420 series. It delivers both electrical and thermal conductivity, making it a go-to solution for shielding, grounding, and masking applications in electrical, HVAC, and industrial assembly environments. The highly malleable lead foil backing conforms to irregular surfaces, complex contours, and detailed patterns with ease. A release film liner supports die-cutting into precise shapes for repeatable manufacturing and assembly workflows. Licensed electricians, HVAC technicians, and industrial maintenance professionals are the primary installers of this tape.

This tape is used in applications requiring conductive masking during electroplating, anodizing, and chemical processing. It also serves as a moisture, weather, UV, and flame barrier in both residential and commercial mechanical systems. Its rubber adhesive bonds reliably to most metal surfaces and a wide range of substrates across varied temperature conditions. The conformable lead backing allows technicians to form the tape around complex geometry without tearing or lifting.

Key Features

• Electrically and thermally conductive lead foil backing for shielding and grounding
• Rubber-based adhesive bonds to most metals and a wide variety of surfaces
• Resists flame, moisture, UV degradation, weather, and many industrial chemicals
• Highly malleable and conformable to complex or detailed surface patterns
• Easy-release film liner supports die-cutting for precise manufacturing applications
• Suitable for electroplating and anodizing masking processes

Compatibility

Designed as a general-purpose electrically and thermally conductive foil tape for use in electrical shielding, HVAC, industrial assembly, and chemical masking applications where a conformable, conductive barrier is required.

Installation Notes

Installation is typically performed by licensed electricians, HVAC technicians, or industrial maintenance technicians depending on the application. De-energize any electrical circuits and shut down associated equipment before applying tape in live panels or shielding assemblies. Ensure surfaces are clean, dry, and free of oils or contaminants before bonding to achieve proper adhesion. Follow all applicable NEC guidelines and facility safety procedures when working in electrical environments.
