3M 7100043961 Double Coated Pet Tape 0.37 in 60 Yd Roll

Product Description

The 3M 7100043961 is a double coated PET tape featuring high-tack adhesive on both sides, mounted on a 74 lb. release liner. Sold as a 0.37-inch-wide roll at 60 yards in length, it is engineered for demanding bonding applications where standard tapes fail. The adhesive system bonds permanently to difficult surfaces, including high surface energy plastics, composite materials, cloth, and insulation facings. HVAC fabricators, insulation contractors, and industrial assembly technicians are the primary installers of this product. It offers strong resistance to UV exposure and elevated temperatures, making it suitable for harsh service environments.

This tape is used in applications that require a permanent, high-strength bond on substrates that are otherwise difficult to adhere to. Typical use cases include laminating, mounting, and splicing operations in both residential and light commercial construction and manufacturing settings. The 74 lb. release liner is moisture stable, protecting the adhesive from heat and humidity until the tape is applied, which allows the adhesive to wet out fully during bonding.

Key Features

• Double coated PET construction with high-tack adhesive on both sides
• Bonds to high surface energy plastics, composites, cloth, and insulation facings
• 74 lb. moisture-stable release liner protects adhesive from heat and humidity prior to application
• High adhesive coat weight supports permanent bonding across a range of environmental conditions
• Excellent UV and temperature resistance for demanding service environments

Compatibility

Designed for use as a high-tack double coated bonding tape on difficult-to-adhere substrates including high surface energy plastics, composite materials, cloth, and insulation facings in industrial and construction applications.

Installation Notes

Surface preparation is critical for optimal adhesive performance — clean and dry the substrate before application. Apply firm, even pressure across the full tape surface to ensure full wet-out contact with the substrate. Remove the release liner only at the time of bonding. Follow all applicable workplace safety guidelines when working with adhesive tapes in confined or high-temperature environments.
