3M 7000049590 Polyester Tape 8905 Blue 27x72yd

Product Description

The 3M 7000049590 is a blue high-temperature polyester tape built for demanding masking and splicing applications in industrial and finishing environments. At 6.5 mil total thickness, it uses a clean-removing silicone adhesive bonded to a tough, non-slivering polyester backing. The tape measures 27 inches wide on a 72-yard roll, providing substantial coverage per roll for large-surface powder coat masking operations. It is designed for use by finishing technicians, industrial painters, and manufacturing personnel who need reliable adhesion through elevated-temperature cure cycles without adhesive residue after removal.

This tape is suited for powder coat paint masking, where surfaces must be protected through high-temperature oven cycles, and for splicing silicone-treated materials where conventional adhesives fail to bond. The non-slivering polyester backing holds up to cutting and handling without edge fraying, making it practical for production-line environments. The 27-inch width is well matched to wide-format masking tasks on flat panels, frames, and structural components before coating.

Key Features

• 6.5 mil (0.17 mm) total thickness with the thickest polyester backing in the 8905 series
• Clean-removing silicone adhesive leaves no residue after high-temperature cure cycles
• Non-slivering polyester backing resists tearing and edge fraying during handling and cutting
• 27-inch width provides wide-format coverage for large masking applications
• 72-yard roll length reduces changeover frequency in production settings
• Designed for bonding and splicing silicone-treated materials where standard tapes do not adhere

Compatibility

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

Installation Notes

Apply to clean, dry surfaces free of oils, dust, and loose coatings before masking. Ensure the tape edges are firmly seated to prevent bleed-through during powder coat application and oven cure. After the cure cycle is complete and the substrate has cooled to a safe handling temperature, remove the tape at a low angle to preserve the clean-remove performance of the silicone adhesive. Follow facility safety procedures when working near powder coat ovens and elevated-temperature equipment.
