3M 7000049101 Lead Foil Tape 420 Silver 0.5 in 36 Yd

Product Description

The 3M 7000049101 is a lead foil tape in the 3M 420 series, designed for applications requiring both electrical and thermal conductivity. The malleable lead foil backing conforms to complex surfaces, curved edges, and detailed patterns, making it well suited for shielding, grounding, and masking tasks in assembly and manufacturing environments. A rubber-based adhesive bonds reliably to most metals and a range of other substrates. An easy-release film liner supports die-cutting into precise shapes. The tape resists flame, moisture, weather, UV degradation, and many chemicals commonly encountered in electroplating and anodizing processes.

This tape is used in industrial and manufacturing settings where a conformable, conductive masking or shielding solution is required. Typical applications include EMI shielding, grounding straps, and masking during electroplating or anodizing operations. The silver-colored lead foil face provides a consistent, conductive surface. It is handled by electricians, electronics assemblers, industrial maintenance technicians, and quality-control personnel in both light and heavy manufacturing facilities.

Key Features

• Electrically and thermally conductive lead foil construction
• Highly conformable — shapes into complex or detailed patterns and accepts die-cutting
• Rubber-based adhesive bonds to most metals and a wide variety of surfaces
• Resists flame, moisture, UV degradation, weathering, and chemicals used in electroplating and anodizing
• Easy-release film liner simplifies handling and precision cutting
• Performs across a wide temperature range

Compatibility

Designed as an OEM-style replacement and general-purpose lead foil tape suitable for industrial shielding, grounding, and masking applications on most metal and hard-surface substrates.

Installation Notes

Applied by electricians or assembly technicians in industrial environments. De-energize any circuit or equipment before applying conductive tape to live components. Clean and dry the target surface before application to ensure full adhesive contact. When die-cutting, use a firm cutting surface and follow all facility safety protocols for handling lead-containing materials, including appropriate PPE and disposal procedures per local regulations.
