3M Specialty High Temperature Masking Tape 501+, Tan, 18 mm x 55 m, 7.3 mil, 48 Rolls/Case

• Holds securely through multiple or extended process cycles
• Low unwind improves handling in wide-width applications
• Remains in place around corners, over contours and irregular surfaces
• Removes cleanly in one piece with no adhesive residue, minimizing unwanted tearing
• Resists paint bleed-through to help create sharp paint lines
• Tan backing tears easily and resists slivering
• Withstands surface temperatures up to 300°F/150°C for 30 minutes

3M Specialty High Temperature Masking Tape 501+ was designed to deliver clean paint lines where surface temperatures can reach up to 300°F/150°C. This tan 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 Industrial Painting
Using our proprietary adhesive, the tape sticks instantly to most surfaces, including metal, rubber and glass, as well as plastic 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 clean paint lines. 

3M™ Specialty High Temperature 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

3M™ Specialty High Temperature Masking Tape 501+ is conformable for easy masking around corners, over irregular surfaces, and offers easy handling that reduces application time. This tape can be qualified for ASTM D-6123 (replaces obsolete PPP-T-42C, Type I, (CID-A-A-883B).

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 and retail industries.

Trusted 3M Brand Quality

The 3M Specialty High Temperature Masking Tape 501+ offers reliable performance backed by the trusted 3M brand. This model is designed specifically for demanding applications, ensuring you get consistent results every time you use it.

Ideal for specialty vehicle and industrial markets, this tape delivers strong holding power and high-temperature resistance, making it a dependable choice for professionals who need precision and durability.

High Temperature Resistance

This masking tape withstands surface temperatures up to 300°F (150°C) for 30 minutes, making it perfect for high-temperature paint baking and other heat-intensive processes. Its tan crepe paper backing maintains integrity without warping or losing adhesion.

Such heat resistance ensures clean paint lines even in tough environments, supporting applications like fascia painting and pipe coating where temperature control is critical.

Precise Size And Format

The tape measures 18 mm wide by 55 meters long, with a thickness of 7.3 mil. This size offers a good balance between coverage and control, allowing for detailed masking work without frequent tape changes.

Sold in cases of 48 rolls, this format suits large projects or ongoing industrial use, providing ample supply for extensive masking tasks without interruption.

Easy Handling And Removal

Thanks to its low unwind force, the tape is easy to handle, especially in wide-width applications. It tears easily by hand, which speeds up application and reduces the need for tools.

When removed, it comes off cleanly in one piece without leaving adhesive residue or tearing, minimizing cleanup time and protecting the underlying surface.

Reliable Paint Line Protection

The tape resists paint bleed-through, helping create sharp, clean paint lines. Its conformable backing adapts well to corners, contours, and irregular surfaces, ensuring consistent masking coverage.

This makes it especially useful for two-tone color applications on vehicles like trucks, buses, and airplanes, where precision and clean edges are essential.
