Premium industrial masking tape for high-temperature paint applications up to 300°F/150°C. Features purple crepe paper backing, high-temperature rubber adhesive, and clean one-piece removal. Ideal for automotive, aerospace, and specialty vehicle painting.
The 3M™ Specialty High Temperature Masking Tape 501+ is a premium industrial masking tape engineered 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 instantly adheres to most surfaces including metal, rubber, glass, plastic, and EPDM-type rubber moldings. Designed specifically for critical paint masking applications in aerospace, automotive, and specialty vehicle markets, this tape delivers exceptional holding power while maintaining clean removal without adhesive residue.
The 501+ tape is ideal for two-tone color applications on specialty vehicles such as trucks, buses, trailers, trains, fire trucks, ambulances, and airplanes. Its proprietary high-temperature rubber adhesive provides ultra-high strength holding power to prevent paint blow-by on a variety of surfaces while resisting paint bleed-through to help create sharp, professional paint lines. The purple backing improves visibility during the masking process, tears easily for convenient application, and resists slivering to ensure one-piece removal without tearing or damage to underlying surfaces.
With a tensile strength of 31 lb/in (543 N/100mm) and 11% elongation at break, this tape conforms perfectly to irregular surfaces, corners, and contours. The low unwind design reduces fatigue and improves productivity in wide-width applications. Each case contains 12 rolls of 55 meters (60.14 yards) length, 72mm (2.83 inches) width, and 6.0 mil thickness, making it an economical choice for high-volume industrial painting operations. The 18-month shelf life ensures product reliability for extended storage.
