Premium aerospace-grade masking tape with rubber adhesive, crepe paper backing, instant adhesion, clean removal, high-temperature resistant, and professional paint line protection for industrial 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 masking tape embodies all the desirable features required for demanding paint masking applications in the aerospace industry. The tape features a natural rubber adhesive that provides instant stick and reliable holding power that resists lifting and curling, ensuring sharp paint lines and professional results.
The smooth mini-crepe paper backing provides excellent surface contact and is solvent and moisture resistant to minimize bleed-through. This conformable backing allows easy masking around corners and over irregular surfaces, reducing application time and labor costs. The tape demonstrates excellent adhesive transfer resistance with clean removal that helps reduce cleanup time and rework. A special backside treatment provides a smooth unwind for easy handling and reduced waste during application.
The crepe paper backing tears easily for tool-free application yet remains strong enough to resist slivering, providing user-friendly one-piece removal. The tape can be certified to ASTM D-6123 standards and is recommended for large-scale paint operations, high-temperature paint bake operations, and aircraft painting applications. With aerospace-level strength and reliability, this masking tape delivers paint flake resistance that reduces contamination and ensures professional paint jobs with minimal rework.
