3M 7100043860 Double Coated Pet Tape 514CW White

Product Description

The 3M 7100043860 is a double coated polyester (PET) tape in the 514CW series, supplied in white and cut to 1.5 inches wide. It carries an acrylic adhesive on both sides of a polyester film backing, allowing it to bond two surfaces together without visible fasteners or liquid adhesives. The tape is built for demanding industrial and fabrication bonding applications where UV exposure and temperature cycling are ongoing concerns. HVAC fabricators, panel builders, and industrial assembly technicians reach for this tape when attaching metals, high surface energy plastics, and composite materials in environments where long-term adhesion is required.

This tape is suited for bonding applications in light industrial assembly, HVAC cabinet and panel fabrication, signage mounting, and composite lamination. The double coated construction makes it effective wherever a clean, structural bond is needed between two rigid or semi-rigid substrates. It performs across a wide temperature range, making it appropriate for both interior and exterior applications that see seasonal temperature swings or direct UV exposure.

Key Features

• Double coated acrylic adhesive on polyester (PET) film backing for structural bonding
• Bonds to metals, high surface energy plastics, and composite materials
• Excellent UV resistance for outdoor or sun-exposed installations
• Performs at both high and low temperature extremes
• Strong peel, tack, and shear strength for demanding load-bearing bonds
• White facing; 1.5 inch width suits standard overlap and panel seam applications

Compatibility

Designed for bonding to metals, high surface energy plastics, and composite materials in industrial and light commercial fabrication applications.

Installation Notes

Surface preparation is critical — clean bonding surfaces of oils, dust, and moisture before applying. Apply firm, even pressure across the full bond area to ensure full adhesive contact. In low-temperature environments, allow the tape and substrates to reach a workable temperature before application to achieve rated adhesion. No special tools are required, but a roller or squeegee is recommended for consistent pressure on larger bond areas.
