3M 7010045145 Polyester Film Tape 850 Silver 4in X 72yd

Product Description

The 3M 7010045145 is a silver polyester film tape with acrylic adhesive, offered in a 4-inch-wide by 72-yard roll at 1.9 mil (0.05 mm) thickness. The polyester film backing provides dimensional stability and a reflective silver finish, while the acrylic adhesive delivers reliable bonding across a range of surfaces and temperatures. This tape is suited for industrial and commercial applications where chemical resistance, reflectivity, and a clean, conformable hold are required. HVAC technicians, electricians, and general trade professionals commonly stock this tape for a variety of light-fabrication and service tasks.

This tape is used for splicing, holding, decorating, color coding, and sealing operations. It performs well in applications where reflective properties are needed, such as light management, duct marking, or surface protection on reflective assemblies. The chemical-resistant construction allows use in environments where exposure to solvents or cleaning agents is a concern. Sold in individual rolls, with a minimum order quantity of 8 rolls per order.

Key Features

• 1.9 mil (0.05 mm) polyester film backing for dimensional stability and tear resistance
• Silver reflective finish suitable for applications requiring light reflection or visual marking
• Acrylic adhesive provides chemical resistance and long-term bonding performance
• 4 inches wide by 72 yards long — full roll format for production or service use
• Suitable for splicing, holding, sealing, color coding, and decorating tasks

Compatibility

Designed as a general-purpose polyester film tape compatible with a wide range of smooth and semi-smooth surfaces in industrial, commercial, and trade service applications where a silver, reflective, chemically resistant adhesive tape is required.

Installation Notes

Surface should be clean, dry, and free of oils or contaminants before application for maximum adhesion. Apply firm pressure along the length of the tape to ensure full contact with the substrate. Cut with scissors or a tape dispenser blade — avoid tearing the film backing, as the polyester construction resists hand-tearing. Store unused rolls in a cool, dry location away from direct sunlight to maintain adhesive performance.
