Temperature Performance

Effective across sub-zero, ambient, and elevated temperature environments

These high-performance aluminum foil tapes are engineered for sealing, shielding, and protective applications across demanding industrial environments. Both AL51 and AL62 utilize a high-shear acrylic adhesive designed for long-term bond integrity, moisture resistance, and vapor barrier performance.

AL51 is a general-purpose, dead-soft aluminum foil tape offering excellent conformability and strong reflective properties for heat and light management. It is commonly used for HVAC duct sealing, surface protection, and maintaining clean, uniform finishes in industrial and processing environments.

AL62 is a thicker, high-strength aluminum foil designed to conform tightly around irregular geometries including fibrous ducting, sheet metal, and complex surfaces. It maintains adhesion and seal integrity even in low-temperature environments, making it ideal for insulation sealing, flashing, and protective use during welding operations.

Both constructions provide reliable sealing, patching, and joining performance while acting as effective moisture and vapor barriers.
