3M 301E Chamois Masking Tape 18mm x 50 m

This masking tape is a crepe-paper product designed for precise masking and temporary adhesion in industrial settings. It provides a controlled release and handling for surface protection, trimming and edge definition during high-temperature processes and routine assembly tasks in automation, electronics, electrical and mechanical environments.

• Rubber-based adhesive delivers 3.6N/cm bond strength for secure hold
• Withstands temperatures up to +149°C for heat-resistant applications
• Thin 0.15mm backing allows accurate conformity to contours
• Tensile strength 24lb/in resists tearing during removal
• Conforms readily to irregular surfaces for clean lines and edges

• Suitable for paint masking and trim protection in bodywork
• Ideal for masking during soldering and thermal processing
• Used for temporary fixing of wiring looms and harnesses
• Can be used for component shielding in assembly lines
• Suitable for edge definition when applying surface coatings

After exposure to high temperatures up to +149°C it releases cleanly from most substrates thanks to the rubber adhesive’s thermal stability, minimising residue on metals and coated surfaces.

Yes, the 18mm width combined with a 0.15mm crepe backing provides fine control for trimming and precise edge work in confined areas.

The crepe paper structure offers flexibility and stretch, enabling the tape to follow complex profiles and maintain contact without lifting.

The tape’s tensile strength of 24lb/in reduces the likelihood of breakage during application or removal in routine industrial handling.
