3M 7100069442 Polyester Film Tape 850 Silver 24in X 72yd

Product Description

The 3M 7100069442 is a silver polyester film tape from the 3M 850 series, featuring a 1.9 mil thick polyester film backing with a pressure-sensitive acrylic adhesive. The silver finish provides reflective properties suited to applications where light or heat reflection is a functional requirement. This tape is sold in a 24-inch wide by 72-yard roll, yielding a large coverage area per roll. It is commonly handled by maintenance technicians, industrial assembly workers, and facilities professionals working in manufacturing, electronics, and general industrial environments.

This tape is used in splicing, holding, sealing, decorating, and color-coding operations across a range of industrial and commercial settings. Its chemical resistance makes it well suited for environments where exposure to solvents or cleaning agents is likely. The reflective silver surface also supports applications where visibility or thermal management is a factor. It performs in both flat and contoured surface applications due to the conformable nature of the polyester film.

Key Features

• 1.9 mil polyester film backing for dimensional stability and tear resistance
• Pressure-sensitive acrylic adhesive provides strong, reliable bonding
• Silver reflective finish suitable for decorating, coding, and reflective applications
• Chemical resistant construction withstands exposure to many common solvents
• 24-inch width by 72-yard length provides high coverage per roll
• Suitable for splicing, holding, sealing, and color-coding tasks

Compatibility

Designed as an industrial-grade polyester film tape for general splicing, sealing, and surface-protection applications across manufacturing, electronics assembly, and facilities maintenance environments.

Installation Notes

Surface preparation is critical before application — clean the substrate free of dust, oil, and moisture for best adhesion. Apply firm pressure across the full tape width using a roller or squeegee to ensure full contact. For splicing applications, confirm alignment before pressing to avoid repositioning, as acrylic adhesive bonds aggressively on contact. Cut with a sharp blade or tape dispenser to achieve clean edges without delaminating the film from the adhesive layer.
