Industrial-grade high-temperature masking tape with purple crepe paper backing, withstands up to 300°F/150°C, ideal for automotive and aerospace paint masking applications with clean removal and no residue.
3M™ Specialty High Temperature Purple Masking Tape 501+ is an industrial-grade masking tape specifically engineered for high-performance industrial painting applications. This premium tape is designed to withstand surface temperatures up to 300°F/150°C for 30 minutes, making it ideal for critical paint masking in aerospace, automotive, and specialty vehicle markets. The tape features a purple crepe paper backing with a high-temperature rubber adhesive that provides ultra-high strength holding power to prevent paint blow-by on a variety of surfaces including metal, rubber, glass, plastic, and EPDM-type rubber moldings.
The 501+ masking tape removes cleanly in one piece with no adhesive residue, minimizing unwanted tearing and damage to underlying surfaces. Its proprietary adhesive formulation ensures instant sticking to most surfaces while maintaining the ability to conform to irregular surfaces, corners, and contours. The purple backing improves visibility during the paint masking process, tears easily for convenient application, and resists slivering for user-friendly, one-piece removal. This tape holds securely through multiple or extended process cycles, making it perfect for complex, multi-stage painting operations.
With a width of 288 mm (11.34 inches) and a length of 55 meters (60.14 yards), this tape is supplied in cases of 4 rolls. The 6.0 mil thickness provides optimal balance between strength and conformability. Ideal applications include high-temperature paint baking, fascia painting, pipe coating, metal fabrication, and automotive truck, bus, and marine paint masking. The low unwind design reduces fatigue and improves productivity for wide-width applications.
