3M 7000028669 Polyester Film Tape 850 Red 1.9 Mil

Product Description

The 3M 7000028669 is a red polyester film tape in the 3M 850 series, constructed with a 1.9 mil polyester film backing and a pressure-sensitive acrylic adhesive. The tape comes in a 1-inch wide by 72-yard roll and is engineered for light industrial and trade applications where dimensional stability, chemical resistance, and clean removability matter. The acrylic adhesive system provides reliable bonding to a range of substrates while resisting moisture and many common chemicals encountered in manufacturing and service environments. Technicians in HVAC, electrical, and general industrial work reach for this tape when they need a thin, conformable film solution.

This tape is suited for splicing, holding, sealing, and color coding tasks across both residential and light commercial settings. Its red color makes it practical for color coding wiring harnesses, duct assemblies, or process lines during installation. The thin 1.9 mil profile keeps it low-profile under insulation or wrapping. It performs reliably in applications where a polyester film tape with chemical resistance is required, and the 72-yard roll length keeps job-site downtime low.

Key Features

• 1.9 mil polyester film backing for dimensional stability and conformability
• Acrylic adhesive system resists moisture and common chemicals
• Red color supports visual color coding in wiring and process applications
• 1-inch width suited for splicing, sealing, and holding tasks
• 72-yard roll length reduces change-out frequency on the job

Compatibility

Designed as a general-purpose polyester film tape for splicing, holding, decorating, color coding, and sealing applications across light industrial and trade environments.

Installation Notes

Apply to clean, dry surfaces free of oil, dust, and loose material for best adhesion. No special tools are required beyond a tape dispenser or utility knife for clean cuts. For electrical or HVAC applications, verify that the tape meets any applicable local code requirements before use as a primary insulating or sealing material. Store unused rolls away from direct sunlight and extreme heat to preserve adhesive performance.
