3M 7010374934 Polyester Tape 8991 Blue 4in X 72yd

Product Description

The 3M 7010374934 is a blue polyester tape with a silicone adhesive backing, sold in a 4-inch-wide by 72-yard roll at 2.4 mil thickness. Designed for high-temperature masking operations, it holds securely during powder coating cycles and performs reliably in flash breaker and bag sealing applications. The silicone adhesive provides clean removal without leaving residue on treated surfaces. This tape is used by industrial finishing professionals, composites fabricators, and skilled tradespeople who need consistent performance under elevated heat conditions.

This tape is suited for a wide range of industrial and manufacturing environments where standard adhesive tapes fail under heat. Common applications include powder coating masking, flash breaker tape in composites layup, and bag sealing processes. It also performs well in splicing, tabbing, and roll-closing operations involving silicone-treated liners or release materials. The 4-inch width makes it practical for covering larger masking areas in a single pass, reducing application time on production or job-site finishing work.

Key Features

• 2.4 mil polyester film backing for strength and conformability under heat
• Silicone adhesive formulation suited for high-temperature masking cycles
• 4-inch width by 72-yard length per roll for efficient coverage
• Clean removal from silicone-treated liners and release materials
• Suitable for powder coating, bag sealing, and flash breaker applications
• Sold per roll with a minimum order quantity of 8 rolls

Compatibility

Designed for use in high-temperature masking, powder coating, composites bag sealing, and splicing applications involving silicone-treated liners or materials.

Installation Notes

Apply to clean, dry surfaces free of oils, dust, and contaminants to ensure proper adhesion. Verify that the substrate and process temperatures are within the tape's rated performance range before use. Remove the tape promptly after the masking cycle is complete to facilitate clean release. No special tools are required for application, but a tape dispenser or applicator can improve consistency on long runs.
