3M™ Metalized Film Tape 8437 is comprised of a relatively thin polyester backing with a metalized coating on both side of the film providing a mirror-like finish with low emissivity and a versatile, long lasting acrylic adhesive. A silicone coated release liner helps with ease of handling and allows for large area applications and die-cutting custom shapes.

Metalized Backing without the Weight
3M™ Metalized Film Tape 8437 is comprised of a 1 mil polyester backing with a metalized coating on both sides of the film to provide a mirror-like finish with low emissivity. It is coated with a versatile, long lasting acrylic adhesive. This backing provides some of the advantages of a metal tape without the associated weight. A mirror-like finish gives the tape high visibility and maintains its bright appearance for up to 3 months. The tape is mounted on a polyester backing that provides long-term aging, high tear resistance, good temperature resistance and high strength. The liner allows for large applications and die-cutting of custom shapes, as well as providing additional stiffness for application in narrow gaps.

Recommended Applications


Splice detection
Applications where reflectivity and low emissivity are desired
Applications requiring a conductive surface
Decorating and identification


Long Last Bond to a Variety of Materials
3M™ Metalized Film Tape 8437 is coated with a transparent acrylic adhesive. This pressure sensitive adhesive grabs on contact, holds securely and features excellent aging properties for a long lasting bond to a variety of materials including metals. This tape can withstand a broad spectrum of temperatures ranging from -60°F/-50°C to 300°F/150°C.

• Metalized surface provides some of the advantages of a metal tape without the associated weight
• Mirror-like finish gives the tape high visibility where it is needed and maintains its bright appearance for up to 3 months
• Thin, high strength polyester film meets low caliper requirements which won't interfere with most machinery processes
• Liner is convenient for die-cutting and applications to large surface areas, or applications where there is a narrow gap
• Abrasion resistance protects surface from abrasion and rough handling
• Pressure sensitive acrylic adhesive for clarity and long-term holding
