3M 7100086190 High Temperature Masking Tape 501 Plus Purple

Product Description

The 3M 7100086190 is a specialty high-temperature purple masking tape engineered for critical paint masking applications where surface temperatures can reach up to 300 degrees F (150 degrees C) for up to 30 minutes. Built on a purple crepe paper backing, this tape delivers ultra-high holding power to prevent paint blow-by on a variety of surfaces. It is designed for use in specialty vehicle, automotive, and industrial painting environments where both thermal resistance and clean removal are required. Licensed tradespeople and automotive paint technicians rely on this tape for demanding, multi-cycle paint operations.

This tape is suited for high-performance industrial painting applications, including two-tone color work on specialty vehicles, fleet graphics, and industrial coating lines. The low-unwind design makes it easier to handle in wide-width applications. Its ability to conform around corners, over contours, and across irregular surfaces makes it a dependable choice for complex masking setups in production or body shop environments.

Key Features

• Withstands surface temperatures up to 300 degrees F (150 degrees C) for 30 minutes
• Removes cleanly in one piece with no adhesive residue
• Ultra-high holding power prevents paint blow-by on varied surfaces
• Resists paint bleed-through for sharp, defined paint lines
• Purple backing improves visibility on the work surface, tears cleanly, and resists slivering
• Conforms around corners, contours, and irregular surfaces
• Low-unwind force improves handling in wide-width applications

Compatibility

Designed for high-temperature paint masking applications in specialty vehicle, automotive, and industrial markets where strong adhesion and thermal resistance up to 300 degrees F are required.

Installation Notes

Apply to clean, dry surfaces free of dust, oil, and loose material to ensure proper adhesion and a clean paint line. Remove tape promptly after the paint process or baking cycle while the tape is still warm to minimize residue risk. Do not exceed the rated temperature or dwell time. Tape application and removal should be performed by trained automotive painters or industrial coating technicians following facility safety protocols.
