3M 7010045014 Polyester Film Tape 850 Silver 3in X 72yd

Product Description

The 3M 7010045014 is a silver polyester film tape from the 3M 850 series, constructed with a 1.9 mil polyester film backing and a pressure-sensitive acrylic adhesive. At 3 inches wide and 72 yards long per roll, it provides extended coverage for demanding trade and industrial applications. The acrylic adhesive system delivers strong, clean adhesion to a wide range of surfaces while resisting many common chemicals. The silver polyester film backing also offers reflective properties that make this tape suitable where visibility or heat reflection is a factor. Licensed tradespeople and technicians in HVAC, electrical, and general maintenance work commonly reach for this tape when splicing, holding, sealing, or color-coding components in environments where standard tape would break down.

This tape is used across a broad range of applications including splicing film and foil materials, holding parts during fabrication or assembly, decorating and color-coding equipment, and sealing in environments with chemical exposure. The reflective surface makes it a practical choice in applications where light reflection or surface marking is required. It is suited for both light industrial and trade service use, including electrical panels, HVAC ductwork areas, and general maintenance tasks where a durable, chemically resistant tape is needed.

Key Features

• 1.9 mil polyester film backing provides dimensional stability and tear resistance
• Pressure-sensitive acrylic adhesive offers strong adhesion and chemical resistance
• Silver finish delivers reflective properties for visibility and heat-reflective applications
• 3 inches wide by 72 yards long — suitable for continuous runs with fewer roll changes
• Suitable for splicing, holding, sealing, decorating, and color-coding tasks
• Resistant to many common chemicals encountered in trade and industrial environments

Compatibility

Designed as a general-purpose polyester film tape for trade and industrial applications requiring a chemically resistant, reflective silver tape on smooth or lightly textured surfaces.

Installation Notes

Surface should be clean, dry, and free of oils or dust before application for optimal adhesion. Apply firm pressure along the full length of the tape to ensure full contact with the substrate. When using in HVAC or electrical environments, follow applicable NEC or local code requirements regarding approved materials for the specific application. Remove existing failed tape completely before applying a fresh length to avoid adhesion loss at overlap points.
