Premium aerospace-grade paint masking tape with rubber adhesive, crepe paper backing, and superior conformability for clean paint lines and easy removal in high-temperature bake 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 multiple bake cycles. This professional-grade masking tape features a natural rubber adhesive that provides instant stick and reliable holding power that resists lifting and curling for sharp, clean paint lines. The smooth mini-crepe paper backing conforms easily to irregular surfaces and corners while maintaining integrity, making it ideal for large-scale paint operations in the aerospace industry and high-temperature paint bake operations.
The tape embodies all desirable features of a premium paint masking tape with aerospace-level strength and reliability. Its natural rubber adhesive offers excellent adhesive transfer resistance with clean removal that helps reduce labor and cleanup. The smooth mini-crepe backing provides excellent surface contact and is solvent and moisture resistant to minimize bleed-through. A special backside treatment provides smooth unwind for easy handling and reduced waste. The tape is easy to tear, aiding in handling, yet strong enough to resist slivering, providing user-friendly one-piece removal.
3M™ Paint Masking Tape 231/231A is conformable for easy masking around corners and over irregular surfaces, offering easy handling that reduces application time. As a professional grade masking tape, it features paint flake resistance that reduces contamination and potential rework, resulting in a professional paint job. The tape can be certified to ASTM D-6123 (replaces obsolete PPP-T-42C, Type I, CID-A-A-883B) and is suitable for aircraft painting and other aerospace applications requiring reliable performance under demanding conditions.
