3M 7100034515 Double Coated Pet Tape 1163MS74 Acrylic

Product Description

The 3M 7100034515 is a double coated PET tape, also identified as 1163MS74, designed for high-tack permanent bonding in demanding industrial and construction applications. It features an acrylic adhesive on both sides, mounted on a 74 lb. release liner. The liner is moisture-stable, protecting the adhesive from heat and humidity until application. This tape delivers strong initial grab and long-term bond strength on difficult surfaces, including high surface energy plastics, composite materials, cloth, and insulation facings. Licensed HVAC fabricators, insulation installers, and industrial assembly technicians are the primary installers of this product.

This tape is engineered for applications where standard pressure-sensitive tapes fall short. It performs reliably on substrates that resist conventional adhesives, including composites and high surface energy plastics. The acrylic adhesive system provides excellent resistance to UV exposure and temperature fluctuations, making it suitable for both indoor assemblies and applications exposed to environmental stress. It is supplied in roll form with a minimum order quantity of one roll.

Key Features

• Double coated acrylic adhesive bonds permanently to high surface energy plastics and composite materials
• Moisture-stable 74 lb. release liner protects adhesive integrity during storage and handling
• High adhesive coat weight supports bonding across a wide range of substrates and environmental conditions
• Excellent UV and temperature resistance for long-term durability in exposed applications
• Performs on difficult surfaces including cloth and insulation facings
• Supplied as a single roll with a minimum order quantity of one

Compatibility

Designed as an OEM-style and industrial replacement double coated tape for bonding applications involving high surface energy plastics, composite materials, cloth, and insulation facings.

Installation Notes

Surface preparation is critical before applying double coated tape — clean and degrease all bonding surfaces to remove dust, oil, and moisture. Apply firm, even pressure across the full tape width after positioning to ensure full contact and adhesive wet-out. Do not stretch the tape during application, as this can reduce bond strength. Removal of the release liner should occur immediately before bonding to prevent contamination of the adhesive layer.
