• Industrial masking tape that is ideal for high performance industrial painting, including two tone color applications on specialty vehicles
• Removes cleanly in one piece with no adhesive residue, minimizing unwanted tearing
• Withstands surface temperatures up to 300°F/150°C for 30 minutes
• Ultra-high strength holding power to prevent paint blow-by on a variety of surfaces
• Holds securely through multiple or extended process cycles
• Low unwind improves handling in wide-width applications
• Resists paint bleed-through to help create sharp paint lines
• Purple backing improves visibility, tears easily and resists slivering
• Remains in place around corners, over contours and irregular surfaces

3M™ Specialty High Temperature Purple Masking Tape 501+ was designed to deliver clean paint lines where surface temperatures can reach up to 300°F/150°C degrees. This purple crepe paper tape is ideal for critical paint masking applications in specialty vehicle, automotive and industrial markets where strong holding and high temperature performance is required.

Ideal for High-Temperature Industrial Painting

Using our proprietary adhesive, the tape sticks instantly to most surfaces, including metal, rubber, glass and plastic, as well as EPDM-type rubber moldings while removing cleanly in one piece. Our high-strength crepe-paper backing conforms to irregular surfaces, resists bleed through from most industrial paint systems, improves visibility during the paint masking process, and helps you achieve sharp paint lines.

3M™ Specialty High Temperature Purple Masking Tape 501+ is an ideal tape for industrial painting, including two-tone color applications on trucks, buses, trailers, trains, fire trucks, ambulances and airplanes. It is easy to tear, which aids in handling, yet strong enough to resist slivering, providing "user friendly," one piece removal. The tape is conformable for easy masking around corners, over contours and irregular surfaces.

Recommended Applications

• High-temperature paint baking
• Fascia painting
• Pipe coating
• Metal fabrication
• Automotive, truck, bus and marine paint masking

What is Masking Tape?

Masking tape was developed specifically to help protect surrounding surfaces from overspray, provide clean paint lines, and remove easily and cleanly when finished. Masking tapes from 3M adhere well, resist solvents or water from the paint, and are strong enough to hang plastic sheeting, yet remove cleanly without damaging the subsurface. The backing, typically crepe paper, can conform to curved and irregular surfaces. The tape hand tears for tool-free application.

A masking tape should specify what surfaces it will stick to and the interval over which it will remove cleanly. A very thin or poorly manufactured tape may demonstrate splintering or shredding, either coming off the roll or when being removed after use. Some masking tapes have the tensile strength for light commercial and industrial applications, including bundling, labeling, sealing, temporary repairs, lane marking, splicing, and surface protection. The classic crepe paper masking tape is a light tan color, but our masking tapes come in a variety of colors and formulations to meet general and specific applications. A roll of masking tape is basic toolbox or supply room item in construction, warehousing, military, marine, shipping, automotive aftermarket, e-commerce, general manufacturing and retail industries.
