Premium aerospace-grade paint masking tape with natural rubber adhesive, crepe paper backing, instant adhesion, clean removal, and superior temperature resistance 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 masking tape combines superior adhesion with clean removal properties, making it ideal for large-scale paint operations in the aerospace industry and high-temperature paint bake operations. The natural rubber adhesive provides instant stick and reliable holding power that resists lifting and curling, ensuring sharp paint lines and professional results.
The tape features a smooth mini-crepe paper backing that conforms easily to corners and irregular surfaces while maintaining integrity throughout the application process. Its excellent adhesive transfer resistance enables clean removal from many surfaces following multi-bake or high-temperature bake cycles, reducing labor and cleanup time significantly. The special backside treatment provides smooth unwind for easy handling and reduced waste, while the strong backing is easy to tear yet resists slivering, providing one-piece removal for user convenience.
This aerospace-level masking tape is solvent and moisture resistant to minimize bleed-through and offers paint flake resistance that reduces contamination and potential rework. Can be certified to ASTM D-6123 standard, replacing the obsolete PPP-T-42C, Type I specification. With a tensile strength of 448 oz/in and maximum operating temperature of 300°F (149°C), this tape delivers exceptional performance for professional painting applications requiring reliability and precision.
