3M 7000047520 Polyester Film Tape 850 Silver 1.9 Mil

Product Description

The 3M 7000047520 is a silver polyester film tape from the 3M 850 series, constructed with a polyester film backing and a pressure-sensitive acrylic adhesive. At 1.9 mil (0.05 mm) thick, it delivers a thin, conformable profile suited for precision applications. The acrylic adhesive provides strong, consistent tack with solid chemical resistance, making it a reliable choice for industrial and commercial work. Licensed tradespeople and maintenance professionals reach for this tape when a dimensionally stable, reflective film tape is required. The roll measures 0.5 inches wide by 72 yards long, offering a practical run length for repetitive tasks.

This tape is used across a range of applications including splicing, holding, decorating, color coding, and sealing. Its reflective silver finish makes it well suited for applications where light reflection or high visibility marking is needed. HVAC technicians, electricians, and industrial maintenance crews commonly use polyester film tape in environments where standard paper or cloth tapes lack the chemical resistance or dimensional stability required. It performs in both indoor and light industrial settings where surface temperatures and exposure to common shop chemicals are a factor.

Key Features

• 1.9 mil polyester film backing for dimensional stability and conformability
• Acrylic adhesive with solid chemical resistance
• Reflective silver finish for visibility marking and decorative applications
• Suitable for splicing, holding, color coding, and sealing tasks
• 0.5 inches wide by 72 yards long for extended use per roll

Compatibility

Designed as a general-purpose polyester film tape for industrial, commercial, and trade applications where a chemically resistant, reflective backing is required.

Installation Notes

Clean and dry all surfaces before applying the tape to ensure full adhesive contact. Apply firm, even pressure along the length of the tape after placement to promote adhesion. When used in splicing or sealing applications, verify that surface temperatures fall within the operating range of acrylic adhesive systems before final installation. No special tools are required, but a tape dispenser is recommended for clean cuts on the 72-yard roll.
