Product Data Sheet

3M™ Specialty High Temperature Purple Masking Tape 501+ is a high-performance masking tape engineered for demanding industrial paint masking applications. Featuring a durable crepe paper backing and a high-temperature rubber adhesive, this tape provides exceptional holding power, clean removal, and precision results in automotive, aerospace, and industrial finishing environments.

Designed to perform in extreme conditions, 3M™ 501+ withstands temperatures up to 300°F (150°C) for short periods, making it ideal for paint bake cycles and other high-heat processes. Its advanced adhesive bonds quickly and securely to a variety hookup surfaces including metal, glass, plastic, and rubber, while removing cleanly in one piece without residue or surface damage.

The strong, conformable crepe paper backing easily adapts to curves, contours, and irregular surfaces, ensuring consistent masking performance across complex geometries. It resists paint bleed-through from most industrial coatings, helping produce crisp, sharp paint lines and reducing the need for rework.

The distinctive purple color improves visibility during application, allowing for precise placement and efficient workflow in high-volume production environments. Its easy-tear design and low unwind force also enhance usability and operator productivity.

Common applications include high-temperature paint baking, two-tone automotive finishes, specialty vehicle painting, metal fabrication, and industrial coating processes. Whether used in automotive refinishing or large-scale manufacturing, 3M™ Specialty High Temperature Purple Masking Tape 501+ delivers reliable performance, durability, and clean results in critical paint masking operations.
