3M 7000138485 High Temp Masking Tape 501 Plus 0.71 in

Product Description

The 3M 7000138485 is a specialty high-temperature masking tape designed to produce clean, sharp paint lines in applications where surface temperatures can reach 300 degrees F for up to 30 minutes. The tan crepe paper backing tears easily by hand, conforms to contours and irregular surfaces, and resists slivering during removal. This tape is built for demanding paint masking work where adhesive residue or paint bleed-through would require costly rework. It is used primarily by automotive painters, specialty vehicle finishers, and industrial coating technicians who need reliable performance through multiple process cycles.

This tape is suited for critical masking applications in automotive refinishing, specialty vehicle production, and general industrial coating environments. Its low-unwind force makes it easier to handle in wide-width applications or when taping large surface areas. The tape holds securely through extended bake or process cycles without lifting, flagging, or leaving adhesive deposits on the substrate.

Key Features

• Withstands surface temperatures up to 300 degrees F for 30 minutes
• Removes cleanly in one piece with no adhesive residue
• Resists paint bleed-through for sharp, defined paint lines
• Conforms to corners, contours, and irregular surfaces without lifting
• Low unwind force improves handling in wide-width or high-volume masking
• Tan crepe paper backing tears cleanly and resists slivering

Compatibility

Designed for high-temperature paint masking applications in specialty vehicle, automotive, and industrial markets where process temperatures reach up to 300 degrees F.

Installation Notes

Surface should be clean, dry, and free of oils or contaminants before tape application. Apply with firm, even pressure to ensure full contact, especially along edges and around contoured surfaces. Remove tape promptly after the process cycle while surfaces are still warm to minimize adhesive transfer. This product is intended for professional use by trained automotive or industrial coating technicians.
