3M 7010312432 Polyester Tape Blue 3in X 72yd 2.4 Mil

Product Description

The 3M 7010312432 is a blue polyester tape with a silicone adhesive backing, engineered for demanding high-temperature masking applications. The tape measures 3 inches wide by 72 yards long with a 2.4 mil total thickness. The polyester film carrier provides dimensional stability under heat, while the silicone adhesive bonds reliably to a range of surfaces without leaving residue. This tape is used primarily in industrial and finishing environments by trade professionals handling powder coating operations, composite fabrication, and liner-handling workflows.

This tape is suited for powder coating and flash breaker or bag sealing applications where conventional acrylic-adhesive tapes would fail under elevated temperatures. It is also used for splicing, tabbing, and roll closing on silicone-treated liners or release materials. The blue color aids visual identification during masking and removal. Both industrial finishers and composite fabricators keep this tape on hand for repetitive high-temperature process work.

Key Features

• Blue polyester film carrier with silicone adhesive for high-temperature resistance
• 2.4 mil total tape thickness for durability during masking and sealing operations
• 3 inches wide by 72 yards long per roll for extended coverage
• Suitable for powder coating masking applications
• Effective for flash breaker and vacuum bag sealing in composite workflows
• Compatible with splicing, tabbing, and roll closing on silicone-treated liners

Compatibility

Designed for use on silicone-treated liners, release materials, and surfaces encountered in high-temperature masking, powder coating, and composite bag sealing applications.

Installation Notes

Application should be performed by trained finishing or fabrication technicians familiar with surface preparation requirements for the specific substrate. Ensure surfaces are clean and free of dust, oils, and moisture before applying the tape. Remove the tape promptly after the process cycle is complete to reduce the risk of adhesive interaction with the substrate at extended dwell times. Follow facility safety protocols when working in heated or pressurized environments.
