Lead Foil Tape, 5 mils w/liner

Series: LF420

5 mil lead foil tape for plating, anodizing & radiation shielding (275°F)

MADE IN THEU.S.A.

Viadon’s 5 mil Lead Foil Tape is engineered for environments where standard rubber-adhesive tapes fail. While most lead tapes (like 3M 420) are rated for 225°F, our acrylic-based adhesive is effective up to 275°F (135°C), providing superior stability in high-heat plating baths and long-term shielding applications.

More About This Product

Why Choose Acrylic Adhesive over Rubber for lead foil tape?

Most users are accustomed to rubber-based lead tapes designed for temporary masking. Viadon’s acrylic adhesive offers distinct advantages for specific industrial needs:

  • - Higher Heat Resistance: Operates safely up to 275°F
  • Superior Solvent Resistance: Does not degrade when exposed to chemicals or plating solutions
  • Permanent Bond Strength: Perfect for moisture barriers, radiation shielding, and permanent x-ray plate applications where a long-term, high-strength bond is required
  • - Acid Resistant: Ideal for electroplating and anodizing environments

Lead Foil Tape Disks, 5 mils on liner

These lead foil tape disks are often used in plating and anodizing masking applications. The significant weight of this metal means these can be used for situations where small amounts of corrective weight is required – for example, golf clubs. The adhesive is a pressure sensitive made from rubber resin. It adheres well to most surfaces, and is bonded to a 5 mils thick lead foil material, wound on a paper release liner. This allows for easy unwinding with a wrinkle-free appearance. NOTE: This tape not designed for clean removal.
