3M 401E Brown Masking Tape 18mm x 50 m

This masking tape is a crepe paper tape designed for temporary surface protection and precise edge definition during painting and high-temperature processes. It combines a flexible paper backing with an elastomeric adhesive to perform in environments where controlled adhesion and heat resistance are required, making it suitable for industrial maintenance and assembly tasks.

• Rubber-based adhesive resists lift during heat exposure
• Maximum operating temperature 140°C allows high-temp use
• Tensile strength 4 N/cm provides secure holding force
• Thickness 0.16 mm ensures clean paint lines and conformability
• Crepe paper backing offers flexibility around contours

• Suitable for automotive paint masking and panel refinishing
• Ideal for masking components during heat treatments
• Used for temporary protection in electrical assembly areas
• Can be used for fixture holding in mechanical workshops
• Used with production line painting processes in automation

The crepe paper backing stretches slightly to follow contours and maintains adhesive contact without splitting, enabling neat edge protection on rounded parts.

After exposure up to the specified operating temperature, the rubber adhesive releases without excessive residue when peeled within typical industrial timeframes, supporting post-process cleaning.

The tape’s crepe structure allows easy tearing by hand or clean cutting with knives, and its width supports controlled placement in narrow access areas.

With a tensile strength of 4 N/cm, it resists elongation under moderate stress, maintaining positional stability on assemblies during handling and processing.
