Aluminum tape is a one-side adhesive tape based on pure aluminum, commonly used for sealing joints between insulating materials and wrapping joints in ventilation, air conditioning and heating duct. It is comprised of an aluminum metal backing with a synthetic elastometric pressure sensitive coating. The adhesive coating is protected by a thin release liner, which is removed prior to application. It may be applied in cold temperatures, yet is very tolerant of temperature extremes. It is an ideal protective coating where abrasion and leak resistance is required.
