3M 7100043799 Double Coated Pet Tape 1/2 in X 60 Yd

Product Description

The 3M 7100043799 is a double coated PET tape, sold under the Venture Tape 1163MS74 series, designed for high-performance bonding in demanding industrial and construction applications. The tape features a high adhesive coat weight on both sides, mounted on a 74 lb. moisture-stable release liner that protects the adhesive from heat and humidity until application. It measures 1/2 inch wide and runs 60 yards per roll. This product is installed by HVAC technicians, insulation contractors, sheet metal workers, and other trade professionals who require a reliable permanent bond to difficult substrates.

This tape is engineered for applications where standard adhesives fail, particularly on high surface energy plastics, composite materials, cloth facings, and insulation facings. It performs across a range of environmental conditions and delivers strong UV and temperature resistance, making it suitable for both indoor mechanical systems and exposed exterior assemblies. Typical use cases include bonding insulation jacketing, securing composite panels, and laminating facing materials in HVAC and building envelope work.

Key Features

• Double coated PET construction provides a permanent, high-strength bond on both adhesive faces
• 74 lb. moisture-stable release liner protects adhesive integrity during storage and handling
• High adhesive coat weight allows the tape to wet-out on difficult surfaces including high surface energy plastics and composite materials
• Excellent UV resistance suits exposed and semi-exposed installation environments
• Strong temperature resistance maintains bond integrity across a wide service range
• Adheres to cloth and insulation facings common in HVAC and mechanical insulation work

Compatibility

Designed as an OEM-style bonding solution for use on high surface energy substrates, composite materials, cloth facings, and insulation facings in HVAC, construction, and industrial assembly applications.

Installation Notes

Surface preparation is critical — substrate surfaces should be clean, dry, and free of oils or dust before application. Apply firm, uniform pressure along the tape length to ensure full wet-out contact with the substrate. Power down or lock out any mechanical system before applying tape in an active HVAC or equipment enclosure. Follow applicable building and mechanical codes for insulation and vapor barrier assemblies where this tape is used as a facing bond.
