Premium aerospace-grade paint masking tape with rubber adhesive, crepe paper backing, and clean removal properties. Ideal for high-temperature bake operations and professional paint 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 smooth masking tape embodies all the features that are desirable in a paint masking tape and is designed specifically for the aerospace market. The natural rubber adhesive provides instant stick and reliable holding power that resists lifting, offering aerospace-level strength and reliability for professional paint operations.
The tape features a smooth mini-crepe backing that provides excellent surface contact and is solvent and moisture resistant to minimize bleed-through. A special backside treatment provides a smooth unwind for easy handling and reduced waste. The crepe paper backing tears easily, offers moderate conformability, and lifts off cleanly. The natural rubber adhesive bonds well to paper, metal, wood and painted surfaces with reliable holding power that resists lifting and curling. Under normal operating conditions, the tape features one-piece removal and is sliver resistant.
3M™ Paint Masking Tape 231/231A is conformable for easy masking around corners, over irregular surfaces, and offers easy handling that reduces application time. As a professional grade masking tape, it has the benefit of paint flake resistance that reduces contamination and potential rework, resulting in a professional paint job. This tape can be certified to ASTM D-6123 (replaces obsolete PPP-T-42C, Type I, (CID-A-A-883B)). The controlled unwind dispenses evenly to help tape more consistently, making it ideal for large scale paint operations in the aerospace industry, high temperature paint bake operations, and aircraft painting applications.
