3M 7000144739 Polyester Tape Blue 48in X 72yd

Product Description

The 3M 7000144739 is a general purpose blue polyester tape engineered for high-temperature masking and splicing applications. Built on a tough, non-slivering polyester film backing at 2.6 mil thickness, it uses a clean-removing silicone adhesive that releases without leaving residue after heat exposure. The roll measures 48 inches wide and 72 yards long, making it well suited for large-surface or continuous-run masking work. HVAC fabricators, industrial painters, and facilities maintenance technicians are the primary installers of this tape in production and service environments.

This tape is designed for powder coat paint masking, where a clean adhesive removal after oven cure is essential to protect finished surfaces. It also performs in splicing applications involving silicone-treated release liners and similar low-surface-energy materials. The wide 48-inch format reduces the number of overlapping passes needed on large panels or sheet metal components, improving masking efficiency in both shop and field environments.

Key Features

• 2.6 mil non-slivering polyester film backing resists tearing during removal
• Clean-removing silicone adhesive leaves no residue after high-temperature exposure
• 48-inch width reduces overlap passes on large panels and sheet metal
• Suitable for splicing silicone-treated and low-surface-energy materials
• Single-roll unit for straightforward inventory and dispensing

Compatibility

Designed for powder coat paint masking and splicing of silicone-treated materials in industrial and fabrication settings where clean adhesive removal after heat cure is required.

Installation Notes

Apply to clean, dry surfaces free of dust, oil, and moisture for best adhesion. Remove the tape promptly after the masking operation is complete, while the substrate is still warm if possible, to support clean adhesive release. No special tools are required beyond a tape cutter or utility knife appropriate to the 48-inch width. Consult the applicable process or safety guidelines for oven temperatures and dwell times specific to the coating operation.
