Start with the application
Describe what the tape must bond, join, seal or hold, including the substrate and how the tape will be applied.

How to Choose Aluminum Foil Tape
A useful specification begins with the complete application—not a model number alone. Use this guide to prepare the information needed to compare Lead Top's standard range.
Selection process
Eight points to confirm.
These steps explain general selection logic. They do not assign a specific Lead Top model to an application without the required operating information.
Choose foil thickness
Foil thickness identifies the aluminum backing gauge. Compare it separately from the complete tape thickness.
Evaluate total tape thickness
Nominal total thickness combines the foil and adhesive layers and excludes the release liner on Lead Top product pages.
Select the acrylic adhesive system
Lead Top supplies water-based and solvent-based acrylic systems. Selection depends on the bonding surface and operating requirement.
Confirm temperature conditions
Provide both application and service temperatures. A temperature range should be confirmed only after the adhesive and full construction are selected.
Check surface compatibility
Identify the substrate, surface finish, cleanliness and whether the surface is flat, curved, smooth or textured.
Decide width and roll length
Widths, roll lengths, cores and packaging are prepared to the confirmed purchasing and production format.
Standard or reinforced construction
Smooth foil tape, scrim reinforcement and fiberglass cloth structures serve different construction requirements. Compare the backing before selecting a model.
