Premium aerospace-grade paint masking tape with natural rubber adhesive, crepe paper backing, instant adhesion, clean removal, and high-temperature resistance up to 300°F for professional painting applications.
3M™ Paint Masking Tape 231/231A is a premium high-performance crepe paper masking tape specifically designed to meet aerospace needs in most painting applications, including the use of multiple bake cycles. This professional-grade tape features a natural rubber adhesive that provides instant stick and reliable holding power that resists lifting, curling, and slivering. The smooth mini-crepe paper backing offers excellent conformability around corners and irregular surfaces while maintaining structural integrity, making it ideal for large-scale paint operations in the aerospace industry.
The tape features exceptional adhesive transfer resistance with clean removal properties that help reduce labor and cleanup time. Its solvent and moisture-resistant backing minimizes bleed-through, ensuring professional paint lines and reducing contamination risk. The special backside treatment provides smooth unwind for easy handling and reduced waste during application. With a tensile strength of 448 oz/in (49 N/100mm) and maximum operating temperature of 149°C (300°F), this tape delivers aerospace-level strength and reliability for demanding paint masking applications.
Designed for professional painters and aerospace manufacturers, 3M™ Paint Masking Tape 231/231A can be certified to ASTM D-6123 standards and offers paint flake resistance that reduces potential rework. The tape tears easily by hand for tool-free application yet maintains one-piece removal without slivering, providing user-friendly operation and consistent results across high-temperature paint bake operations.
