Premium aerospace-grade paint masking tape with natural rubber adhesive, crepe paper backing, instant adhesion, clean removal, and multi-bake capability for professional painting applications.
3M™ Paint Masking Tape 231/231A is a premium high-performance crepe paper masking tape specifically engineered to meet rigorous aerospace standards and requirements. This professional-grade masking tape is designed for the most demanding painting applications, including multiple bake cycles and high-temperature operations. The tape features a natural rubber adhesive that provides instant stick and reliable holding power that resists lifting and curling, ensuring sharp, clean paint lines with minimal bleed-through.
The smooth mini-crepe paper backing offers excellent surface contact and conformability, allowing the tape to easily mold around corners and irregular surfaces without compromising integrity. The backing is inherently solvent and moisture resistant, which minimizes paint bleed-through and ensures clean, professional results. A special backside treatment provides smooth unwind characteristics 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 provide one-piece removal for user-friendly operation.
3M™ Paint Masking Tape 231/231A delivers aerospace-level strength and reliability with excellent adhesive transfer resistance and clean removal properties that help reduce labor and cleanup time. This tape demonstrates paint flake resistance that reduces contamination and potential rework, resulting in superior professional paint jobs. It can be certified to ASTM D-6123 standards and is ideal for large-scale paint operations in the aerospace industry, high-temperature paint bake operations, and aircraft painting applications. The tape bonds reliably to paper, metal, wood, and painted surfaces while maintaining consistent performance under normal operating conditions.
