3M 7100043857 Double Coated Pet Tape 2 in 60 Yd

Product Description

The 3M 7100043857 is a double coated PET tape designed for high-performance bonding in demanding industrial and construction applications. It features a high-tack adhesive on both sides, mounted on a 74 lb. release liner that protects the adhesive from heat and humidity until application. The tape is 2 inches wide and 60 yards long, engineered to bond permanently to difficult substrates including high surface energy plastics, composite materials, cloth, and insulation facings. Its construction provides strong resistance to UV exposure and temperature variation, making it reliable in harsh environmental conditions.

This tape is suited for commercial and industrial applications where a permanent, high-strength bond is required on difficult-to-adhere surfaces. Typical use cases include laminating, mounting, and assembly operations involving plastics, composites, and faced insulation materials. The moisture-stable release liner allows the adhesive to wet out properly during bonding, supporting consistent adhesion across a range of environmental conditions. It is commonly used by insulation contractors, fabricators, and industrial assembly technicians.

Key Features

• Double coated PET film carrier with high-tack adhesive on both sides for permanent bonding
• 74 lb. release liner protects adhesive from heat and humidity prior to application
• High adhesive coat weight supports adhesion to high surface energy plastics, composites, cloth, and insulation facings
• Excellent UV resistance for outdoor or exposed installations
• Strong temperature resistance for use in thermally demanding environments
• 2-inch width and 60-yard length per roll for efficient coverage on larger jobs

Compatibility

Designed for bonding applications involving high surface energy plastics, composite materials, cloth substrates, and insulation facings where a high-tack, permanent double coated tape is required.

Installation Notes

Surface preparation is critical for optimal adhesion — clean and dry the substrate thoroughly before applying the tape. Remove the release liner just before bonding and apply firm, even pressure across the full tape width to promote wet-out. This tape is intended for permanent bonding; repositioning after adhesive contact is not recommended. Follow all applicable safety data sheet guidelines when working with adhesive tapes in confined or poorly ventilated spaces.
