3M 7100043945 Double Coated Pet Tape 1163MS74 0.25in 60yd

Product Description

The 3M 7100043945 is a double coated PET tape, sold under the 1163MS74 product line, designed for high-demand bonding applications in industrial and commercial settings. It features a high adhesive coat weight on both sides, mounted on a 74 lb. release liner that protects the adhesive from heat and humidity until application. The tape measures 0.25 inches wide and 60 yards long per roll. It delivers strong, permanent bonds to a wide range of substrates including high surface energy plastics, composite materials, cloth, and insulation facings. Licensed tradespeople and industrial assembly technicians are the primary installers.

This tape is suited for demanding assembly and fabrication environments where conventional adhesives or lower-tack tapes fall short. It performs reliably on difficult-to-bond surfaces such as high surface energy substrates and composite panels. The construction provides excellent resistance to UV exposure and temperature variation, making it appropriate for both indoor and outdoor bonding scenarios. It is commonly used in HVAC insulation facing attachment, panel assembly, and general industrial laminating applications.

Key Features

• Double coated PET construction with high adhesive coat weight for permanent bonding
• 74 lb. release liner preserves adhesive integrity against heat and humidity prior to application
• Bonds to high surface energy plastics, composites, cloth, and insulation facings
• Excellent UV resistance for outdoor or exposed installations
• Strong temperature resistance across a range of environmental conditions
• 0.25 inch width suited for precision bonding lines and narrow-profile assemblies

Compatibility

Designed as an OEM-style replacement and general-use double coated PET tape for industrial bonding, HVAC insulation facing, composite panel assembly, and similar demanding adhesive applications.

Installation Notes

Surface preparation is critical before application — clean, dry, and degrease all substrate surfaces for maximum adhesion. Peel the release liner just prior to application to avoid contaminating the adhesive. Apply firm, even pressure across the full bond area to ensure full wet-out contact with the substrate. This product is intended for professional installation in controlled or field fabrication environments.
