Premium industrial masking tape for high-temperature paint applications up to 300°F/150°C. Purple crepe paper with high-temperature rubber adhesive. Removes cleanly without residue. 24mm x 55m rolls, 36 per case.
The 3M™ Specialty High Temperature Masking Tape 501+ is a premium industrial masking solution designed for high-performance painting applications where surface temperatures reach up to 300°F/150°C. This purple crepe paper tape features a high-temperature rubber adhesive that provides instant stick to most surfaces including metal, rubber, glass, plastic, and EPDM-type rubber moldings. The tape is specifically engineered for critical paint masking applications in aerospace, automotive, and specialty vehicle markets, delivering clean paint lines and professional results.
This industrial-grade tape removes cleanly in one piece with no adhesive residue, minimizing unwanted tearing and surface damage. The ultra-high strength holding power prevents paint blow-by on a variety of surfaces while maintaining secure adhesion through multiple or extended process cycles. The purple backing improves visibility during the masking process, tears easily for convenient application, and resists slivering for user-friendly removal. With low unwind characteristics, this tape improves handling in wide-width applications and reduces operator fatigue during extended use.
The 3M™ Specialty High Temperature Masking Tape 501+ is ideal for high-temperature paint baking, fascia painting, pipe coating, metal fabrication, and automotive, truck, bus, and marine paint masking. The conformable crepe paper backing allows for easy masking around corners, over contours, and irregular surfaces, while resisting paint bleed-through from most industrial paint systems. Each case contains 36 rolls, making it economical for high-volume industrial operations.
