Premium aerospace-grade masking tape with natural rubber adhesive, crepe paper backing, instant adhesion, clean removal, and superior paint line sharpness for professional painting operations.
3M™ Paint Masking Tape 231/231A is a premium high-performance crepe paper masking tape specifically designed to meet aerospace industry needs in paint applications, including multiple bake cycles and high-temperature operations. This professional-grade masking tape features a natural rubber adhesive that provides instant stick and reliable holding power, resisting lifting and curling for sharp, clean paint lines. The smooth mini-crepe paper backing conforms easily to corners and irregular surfaces while maintaining structural integrity, making it ideal for complex masking requirements in aerospace painting operations.
The tape's natural rubber adhesive bonds exceptionally well to paper, metal, wood, and painted surfaces, offering excellent adhesive transfer resistance and clean removal that minimizes labor and cleanup time. Its special backside treatment ensures smooth unwind for easy handling and reduced waste during application. The tape is easy to tear by hand, eliminating the need for tools, yet strong enough to resist slivering and provides one-piece removal for user convenience. With a tensile strength of 448 oz/in and maximum operating temperature of 149°C (300°F), this tape is certified to ASTM D-6123 standards and replaces obsolete PPP-T-42C specifications.
Designed for large-scale paint operations in the aerospace industry, this masking tape delivers paint flake resistance that reduces contamination and potential rework, ensuring professional-quality paint jobs. The controlled unwind dispenses evenly to help tape more consistently, and the tape removes cleanly from many surfaces following multi-bake or high-temperature bake cycles. With 36 rolls per case, each roll measuring 1 inch wide by 60 yards long with 7.6 mil thickness, this product represents an economical choice for high-volume aerospace painting operations.
