3M 7010045037 Polyester Film Tape 850 Silver 3/8in X 72yd

Product Description

The 3M 7010045037 is a silver polyester film tape in the 3M 850 series, constructed with a 1.9 mil polyester film backing and an acrylic adhesive system. At 3/8 inches wide and 72 yards long per roll, it delivers a high surface-area-to-width ratio suited for detailed masking, splicing, and sealing tasks. The acrylic adhesive provides solid adhesion across a range of surfaces while the polyester film carrier resists many common chemicals. The silver finish also offers reflective properties, making this tape useful in applications where visibility or light reflection is a functional requirement. Installers and technicians across electrical, industrial, and light fabrication trades use this tape for its combination of dimensional stability, chemical resistance, and clean appearance.

This tape is suited for use in electrical panel work, electronics assembly, light industrial fabrication, and general trade maintenance. Its narrow 3/8 inch width makes it practical for precise splicing of films or foils, color coding of wiring or components, decorating finished surfaces, and sealing lightweight joints or seams. The reflective silver surface is appropriate for applications where marking visibility is important. It is sold by the roll and is commonly purchased in quantity for shop or field use.

Key Features

• 1.9 mil polyester film backing provides dimensional stability and tear resistance
• Acrylic adhesive system bonds to a variety of surfaces with consistent tack
• Chemical resistant construction suitable for industrial environments
• Silver finish provides reflective properties for visibility and decorative applications
• 3/8 inches wide by 72 yards long per roll for extended coverage on narrow applications
• Suitable for splicing, sealing, color coding, holding, and decorating tasks

Compatibility

Designed as an OEM-style replacement and general-use polyester film tape suitable for electrical, industrial, and light fabrication applications requiring a narrow silver reflective tape with acrylic adhesive.

Installation Notes

Surface preparation is critical for consistent adhesion — clean and dry the substrate before application. For electrical or panel work, follow applicable NEC guidelines and de-energize circuits before applying tape near live conductors. Avoid stretching the tape during application to maintain dimensional accuracy. Store unused rolls away from direct heat and moisture to preserve adhesive performance.
