3M 7100034513 Double Coated Pet Tape 1163MS74 Acrylic

Product Description

The 3M 7100034513 is a double coated PET tape in the 1163MS74 series, engineered for high-demand bonding applications across industrial and construction trades. It uses a high-tack acrylic adhesive on both faces, mounted on a 74 lb. release liner that protects the adhesive from heat and humidity until application. The tape is designed to wet out firmly against difficult substrates, including high surface energy plastics, composite materials, cloth, and insulation facings. Its acrylic adhesive system delivers strong UV resistance and broad temperature resistance, making it suitable for assemblies exposed to outdoor or thermally variable environments. The roll measures approximately 56.5 inches in length at 55.94 inches wide.

This tape is intended for bonding applications where conventional fasteners or liquid adhesives are impractical. Typical use cases include laminating insulation facings, mounting composite panels, and sealing or joining materials with challenging surface chemistries. The high adhesive coat weight supports permanent bonds across a range of environmental conditions, including humid or high-temperature settings. It is well suited for use by HVAC fabricators, industrial maintenance technicians, and sheet metal contractors working with duct liner, panel facings, or specialty substrates.

Key Features

• Double coated PET construction with high-tack acrylic adhesive on both faces
• 74 lb. release liner protects adhesive from heat and humidity prior to application
• High adhesive coat weight for permanent bonds to difficult substrates
• Excellent UV resistance for outdoor or exposed installations
• Broad temperature resistance suitable for thermally demanding environments
• Bonds to high surface energy plastics, composites, cloth, and insulation facings

Compatibility

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

Installation Notes

Surface preparation is critical for maximum bond strength — clean, dry, and debris-free surfaces are required before application. Apply firm, uniform pressure across the tape after positioning to ensure full wet-out contact with the substrate. Remove the release liner only at the moment of bonding. No cutting tools beyond standard safety blades are required; consult applicable facility or trade safety guidelines when working with adhesive-backed materials in confined or enclosed spaces.
