3M 8905 Blue Masking Tape 2in x 66 m

This masking tape is a silicone-based polyester tape designed for temporary protection and precise masking in high-temperature industrial settings. It is intended for use where heat resistance and clean removal are required during processes such as thermal treatments, coating operations and precision assembly.

• Silicone adhesive delivers strong initial tack and secure adhesion
• Withstands temperatures from −60°F to +400°F for thermal processes
• Polyester backing offers dimensional stability under heat
• Tensile strength of 110 lb/in resists tearing during handling
• Thickness of 0.162 mm ensures controlled conformability and edge definition
• Adhesion measured at 4 N/cm supports reliable stick on varied substrates

• Suitable for high-temperature paint-bake cycles in component finishing
• Ideal for masking during wave or reflow soldering in electronics assembly
• Used for protecting surfaces during heat treatment in metalwork
• Can be used for precise edge definition in automated painting lines
• Used with thermal insulation tasks requiring temporary secure hold

Each roll measures 65.83 m, enabling extended runs in production before replacement and reducing machine downtime for tape changes.

The tape is supplied at 2 in width, compatible with many industrial masking dispensers and automated masking stations.

The polyester backing maintains dimensional stability when exposed to repeated temperature cycles within the stated operating range, minimising lift or distortion.

Performance testing aligns with recognised ASTM methods for adhesive strength, peel behaviour and backing properties used in industrial evaluation.
