Premium aerospace-grade masking tape with rubber adhesive, crepe paper backing, and high-temperature resistance for professional paint operations and aircraft applications.
3M™ Paint Masking Tape 231/231A is a premium high-performance crepe paper masking tape engineered specifically for aerospace applications and professional painting operations. This advanced masking tape features a natural rubber adhesive that provides instant adhesion and reliable holding power, resisting lifting and curling to ensure sharp, clean paint lines. The smooth mini-crepe paper backing delivers excellent surface contact while remaining solvent and moisture resistant to minimize paint bleed-through, making it ideal for multi-bake and high-temperature paint operations.
Designed for large-scale aerospace painting applications, this professional-grade masking tape combines aerospace-level strength with user-friendly handling. The tape's special backside treatment provides smooth unwinding for easy application and reduced waste, while the crepe paper backing tears easily without slivering, ensuring one-piece removal that protects underlying surfaces. With a maximum operating temperature of 300°F (149°C), this tape maintains its integrity through demanding bake cycles while delivering paint flake resistance that reduces contamination and potential rework.
The 18mm width tape comes in a case of 48 rolls, each measuring 55 meters in length with a 7.6 mil thickness. Its conformable design allows for easy masking around corners and over irregular surfaces, reducing application time while providing professional-quality results. Certified to ASTM D-6123 standards, this tape is the industry standard for aerospace painting, aircraft maintenance, and high-performance industrial applications where precision and reliability are non-negotiable.
