3M 7010373540 Lead Foil Tape 420 5 Inch X 36 Yd

Product Description

The 3M 7010373540 is a lead foil tape in the 420 series, designed for applications requiring electrical and thermal conductivity. The dark silver tape uses a rubber-based adhesive that bonds well to most metals and a wide range of surfaces. Its highly malleable lead foil backing conforms to complex shapes, contours, and detailed patterns, making it suited for assembly, manufacturing masking, and shielding applications. The tape ships with an easy-release film liner that supports die-cutting into precise shapes. It resists flame, moisture, UV degradation, weather exposure, and many chemicals used in electroplating and anodizing processes.

This tape is used in industrial manufacturing and assembly environments where electrically or thermally conductive masking or shielding is required. Typical applications include EMI and RFI shielding, radiation shielding, chemical masking during electroplating and anodizing, and thermal management in electronics assembly. Its conformability makes it a practical choice for irregular surfaces or intricate part geometries. Installation is performed by manufacturing technicians, electronics assemblers, and industrial maintenance professionals.

Key Features

• Electrically and thermally conductive lead foil backing
• Rubber-based adhesive bonds to most metals and a variety of surfaces
• Highly conformable and malleable — shapes to complex or irregular contours
• Easy-release film liner supports die-cutting into specific shapes for production processes
• Resists flame, moisture, weather, UV degradation, radiation, and common electroplating and anodizing chemicals
• Performs across a wide temperature range

Compatibility

Designed for use on most metal surfaces and other substrates common in industrial assembly, electroplating masking, anodizing masking, and EMI or RFI shielding applications.

Installation Notes

Applied by hand or with standard tape dispensing tools in manufacturing, assembly, or maintenance settings. Surface should be clean, dry, and free of oils or contaminants before application to ensure proper adhesion. When die-cutting, use the included film liner to maintain shape integrity during cutting and handling. Follow all applicable facility safety protocols when handling lead-containing materials, including appropriate PPE per local occupational health and safety regulations.
