3M 8905 Blue Masking Tape 25.4mm x 66 m

This masking tape provides a high-temperature masking solution for industrial processes where silicone adhesion and polyester support are required. It is designed for use in controlled manufacturing and surface-finishing environments, offering a coloured barrier that withstands elevated and reduced temperatures while facilitating precise masking operations.

• Silicone-based adhesive delivers removable, residue-free performance
• Polyester backing offers dimensional stability under heat
• Withstands operating range from -60°F to +400°F, enabling extreme conditions
• Tensile strength of 110 lb/in ensures tear resistance during handling
• Thickness 0.162 mm provides consistent edge integrity for fine outlines
• Blue colour improves Visual contrast for accurate masking

• Suitable for powder coating edges and masking panels in finishing lines
• Ideal for automotive paint preparation and trim protection tasks
• Used for thermal masking of components in electronics assembly
• Can be used for masking in ovens and curing processes in production
• Used for precision masking in mechanical fabrications and assemblies

The silicone adhesive maintains adhesion at elevated temperatures and can be removed without significant residue after exposure within its temperature limits.

The polyester backing combines flexibility with sufficient stiffness to allow accurate positioning and clean tear control at application edges.

Store in a cool, dry location away from direct sunlight to maintain adhesive properties and backing stability until use.

The 25.4 mm width offers a consistent visible edge for narrow masking lines and repeatable application in assembly routines.

The material balance between silicone adhesive and polyester backing permits conforming to moderate curves while retaining edge definition.
