3M 8985L Purple Masking Tape 12in x 72

This masking tape is a polyester-backed adhesive tape designed for precise masking tasks in industrial settings. It provides a thin-profile solution for temporary surface protection and accurate edge definition during painting and finishing operations where a controlled peel and heat tolerance are required.

• Rubber-based adhesive delivers 2.5 N/cm adhesion for secure hold
• Polyester backing offers 123.4 N/25mm tensile strength for dimensional stability
• Withstands temperatures up to 93°C for high-temperature processes
• Thin 0.1mm profile enables precision masking and minimal edge build-up
• Available in a long 72 yd roll to reduce changeovers during production

• Suitable for automotive paint requiring heat resistance
• Ideal for electronics assembly during conformal coating and curing
• Used for electrical component masking in high-temperature operations
• Can be used for mechanical finishing where precise paint lines are needed

The adhesive maintains bond up to 93°C and the polyester backing preserves dimensional integrity during elevated temperature exposure, reducing creep and edge lift.

At 0.1mm thickness the tape minimises shadowing and ensures a Sharp paint edge while occupying minimal gap space on delicate components.

The polyester substrate yields a tensile strength of 123.4 N/25 mm, allowing reliable tensioning and tear resistance when applied or removed.

The rubber adhesive gives an adhesion force of 2.5 N/cm, balancing secure adhesion with controllable removal for temporary masking tasks.
