3M 7010335763 Polyester Tape 8991 Blue 0.5in X 72yd 2.4 Mil

Product Description

The 3M 7010335763 is a blue polyester film tape with a silicone adhesive backing, engineered for high-temperature masking and processing applications. The 2.4 mil total thickness gives the tape enough body to resist tearing during application and removal, while the silicone adhesive maintains bond integrity through elevated heat cycles. Each roll measures 0.5 inches wide by 72 yards long. This tape is used in industrial and finishing environments by painters, powder coaters, composites technicians, and manufacturing line operators who need a tape that holds through oven or cure-cycle temperatures without adhesive transfer or edge bleed.

Primary applications include powder coating masking, where the tape protects threads, bores, and finished surfaces from coating overspray during oven cure. It is also widely used in flash breaker and vacuum bag sealing operations in composites fabrication. Secondary uses include splicing, tabbing, and roll-closing silicone-treated liners and release materials. The tape performs in both light industrial and production-scale settings wherever a clean-release, heat-stable masking solution is needed.

Key Features

• Silicone adhesive resists adhesive transfer and edge bleed during high-temperature cycles
• 2.4 mil polyester film backing provides consistent tensile strength and conformability
• 0.5 inch width suited for masking narrow features such as threads, edges, and small bores
• 72-yard roll length reduces changeover frequency on production lines
• Suitable for flash breaker and vacuum bag sealing in composites work
• Compatible with splicing and tabbing of silicone-treated liner materials

Compatibility

Designed for high-temperature masking applications including powder coating ovens and composites cure cycles. Suitable for use on silicone-treated liners and release materials requiring a clean-release, heat-stable tape.

Installation Notes

Apply to clean, dry, and grease-free surfaces for best adhesion and clean removal. Press the tape edge firmly to prevent coating bleed under the tape edge during powder coating or oven cure. After the heat cycle, allow the part to cool to a safe handling temperature before removing the tape to reduce the risk of surface damage. No special tools are required for application; use a tape dispenser or knife for clean cuts.
