3M 7100065925 Polyester Film Tape 850 2in X 72yd

Product Description

The 3M 7100065925 is a transparent polyester film tape — sold as 3M Polyester Film Tape 850 — measuring 2 inches wide by 72 yards long with a 1.9 mil film thickness. The backing is a high-clarity polyester film paired with an acrylic adhesive system. This combination delivers clean, consistent adhesion on a wide range of surfaces. Technicians use it for splicing, holding, sealing, and surface protection in applications where chemical resistance and optical clarity matter. The 1.9 mil construction keeps the tape thin and conformable while maintaining dimensional stability under moderate stress.

Polyester Film Tape 850 is suited for industrial and commercial environments where a transparent, chemically resistant tape is required. Typical applications include film and foil splicing, masking during coating or plating operations, cable harnessing, and surface protection on finished parts. The acrylic adhesive holds well across a range of temperatures and resists many common solvents and process chemicals, making it a reliable choice for production and maintenance operations.

Key Features

• 1.9 mil polyester film backing for dimensional stability and conformability
• Acrylic adhesive system with chemical resistance to many solvents and process chemicals
• High-clarity transparent film for applications requiring visibility through the tape
• Suitable for splicing, holding, sealing, and surface protection
• Sold per roll: 2 inches wide by 72 yards long

Compatibility

Designed as a general-purpose polyester film tape for industrial, commercial, and maintenance applications requiring chemical resistance and optical clarity.

Installation Notes

Application surface should be clean, dry, and free of dust, oil, or loose material before tape is applied. Firm pressure across the full tape width during application helps ensure full adhesive contact. For splicing or precision-hold applications, verify the tape width and adhesive chemistry are appropriate for the substrate before committing to a production run.
