3M 7100034512 Double Coated Pet Tape 53.97 in Acrylic

Product Description

The 3M 7100034512 is a double coated PET tape with high-tack acrylic adhesive on both sides, mounted on a 74-pound release liner. It is engineered for demanding bonding applications where conventional tapes fall short. The tape delivers strong permanent adhesion to high surface energy plastics, composite materials, cloth, and insulation facings. It is designed with built-in resistance to UV exposure and temperature extremes, making it a dependable solution in environments where adhesive breakdown is a common failure point. HVAC fabricators, insulation contractors, and industrial assembly technicians are the primary installers of this product.

This tape is suited for both residential and commercial applications that require a permanent, high-strength bond to difficult substrates. Typical use cases include bonding insulation facings in duct assemblies, attaching composite panels, and securing materials in environments with variable humidity or heat. The moisture-stable release liner protects the adhesive during storage and staging, allowing the tape to wet out fully during the bonding process. It performs across a range of environmental conditions, including applications where UV exposure or elevated temperatures could degrade lesser adhesive systems.

Key Features

• Double coated PET construction with high-tack acrylic adhesive on both sides
• 74-pound moisture-stable release liner protects adhesive from heat and humidity before application
• High adhesive coat weight enables permanent bonding to a wide variety of substrates
• Adheres to difficult surfaces including high surface energy plastics, composites, cloth, and insulation facings
• Excellent UV and temperature resistance for long-term performance in demanding environments

Compatibility

Designed for bonding applications involving high surface energy plastics, composite materials, cloth, and insulation facings in industrial, construction, and HVAC assembly contexts.

Installation Notes

Surface preparation is critical — clean and dry the substrate thoroughly before applying the tape to ensure full adhesive contact. Apply firm, even pressure across the full bonded area to allow the adhesive to wet out properly. In HVAC or insulation applications, follow applicable mechanical codes and manufacturer guidelines for the assembly being constructed. Do not expose the release liner side to adhesive contamination before bonding.
