3M 7100077066 Polyester Film Tape 850 Black 0.75in X 72yd

Product Description

The 3M 7100077066 is a black polyester film tape from the 3M 850 series, combining a 1.9 mil polyester film backing with an acrylic adhesive system. At 0.75 inches wide and 72 yards long per roll, it delivers consistent, long-length coverage for industrial and light trade applications. The acrylic adhesive provides strong initial tack and bonds firmly to smooth and semi-smooth surfaces. The polyester film construction offers chemical resistance and dimensional stability under temperature variation, making it a practical choice for splicing, holding, sealing, color coding, and light decorative marking in shop, field, or panel environments.

This tape is suited for electrical, HVAC, and general industrial use where a thin, conformable film tape is needed for repetitive tasks. Common applications include wire harness identification, panel labeling, light-duty splicing of films and foils, and temporary or permanent sealing of packaging or components. The black color supports color-coding schemes in multi-circuit or multi-system installations. It is used by electricians, HVAC technicians, and maintenance trades in both residential and commercial settings.

Key Features

• 1.9 mil polyester film backing for thin-profile, conformable coverage
• Acrylic adhesive with strong tack on smooth and semi-smooth surfaces
• Chemical resistant construction handles exposure to common shop chemicals
• Black color supports color-coding and circuit identification workflows
• 72-yard roll length reduces change-outs during high-volume tasks
• Suitable for splicing, holding, sealing, decorating, and color coding

Compatibility

Designed as a general-purpose polyester film tape for use on smooth and semi-smooth surfaces in electrical, HVAC, and industrial maintenance applications where a thin, chemically resistant film tape is required.

Installation Notes

Surface should be clean, dry, and free of oils or contaminants before application to ensure full adhesive contact. Apply with firm, even pressure across the tape width to seat the adhesive. For electrical identification or labeling use, verify that the tape material and adhesive are appropriate for the operating temperature range of the installation. Remove the roll from service if the backing shows signs of delamination or adhesive transfer failure.
