3M 7000049584 Polyester Tape Blue 18in X 72yd

Product Description

The 3M 7000049584 is a general purpose blue polyester tape designed for high-temperature masking and splicing applications. It combines a tough, non-slivering polyester film backing with a clean-removing silicone adhesive that holds securely during thermal cycles and releases without leaving residue. The tape measures 18 inches wide by 72 yards long and carries a total thickness of 2.6 mil (0.066 mm). It is well suited for industrial and finishing environments where a reliable, residue-free tape is required after exposure to elevated temperatures. Licensed HVAC technicians, industrial painters, and finishing technicians are the typical installers and users of this product.

This tape is used primarily for powder coat paint masking, where surfaces must be protected during the coating and curing process without adhesive transfer. It also serves in splicing silicone-treated release liners and similar low-surface-energy films where standard adhesive tapes fail to bond or release cleanly. The 18-inch width makes it appropriate for masking larger surface areas in a single pass, reducing tape overlap and saving labor time in production or field finishing environments.

Key Features

• Clean-removing silicone adhesive leaves no residue after high-temperature exposure
• Non-slivering polyester film backing resists tearing and splitting during removal
• 2.6 mil total thickness provides durability without excessive bulk
• 18-inch width supports large-area masking in fewer passes
• Suitable for splicing silicone-treated and low-surface-energy materials
• Blue color provides clear visual contrast against masked surfaces for accurate application and removal

Compatibility

Designed for powder coat paint masking and splicing of silicone-treated materials in industrial and finishing applications.

Installation Notes

Apply this tape to clean, dry surfaces free of oils, dust, and loose particles for best adhesion and clean removal. Ensure the substrate surface temperature is within the tape's rated operating range before application. When used for powder coat masking, remove the tape promptly after the curing cycle while the part is still warm to minimize adhesive transfer risk. No special tools are required for application, though a tape dispenser or roller may improve uniformity on large surfaces.
