3M 7000049601 Masking Tape 18 Mm 72 Yd Blue Silicone

Product Description

The 3M 7000049601 is a high-temperature masking tape built for demanding industrial and manufacturing applications. The tape combines a blue polyester film backing with a silicone adhesive system, producing a 3.5 mil thick, 18 mm wide roll that runs 72 yards (215 feet) in length. With a tensile strength of 46 lb per inch, the backing resists tearing, abrasion, and chemical exposure without slivering or fragmenting during removal. It is designed for technicians and assemblers working in environments where standard paper masking tapes fail due to heat, solvents, or mechanical stress.

This tape is rated for continuous use from -60 degrees F up to 400 degrees F (204 degrees C), making it well suited for powder coating, anodizing, electroplating, and oven bake cycles in industrial settings. Primary applications include holding and splicing operations where a clean, residue-free removal is required after thermal processing. The tape releases cleanly from stainless steel, anodized aluminum, and glass after a 5-hour bake cycle at 350 degrees F (177 degrees C), preserving surface integrity on finished parts.

Key Features

• Silicone adhesive rated to 400 degrees F continuous service temperature
• 46 lb per inch tensile strength with tear-resistant, non-slivering polyester film backing
• Abrasion-resistant and chemical-resistant construction for industrial process environments
• Removes cleanly from stainless steel, anodized aluminum, and glass after a 5-hour bake at 350 degrees F
• Operating range spans -60 degrees F to 400 degrees F for both cold and high-heat applications
• Series 8902 formulation designed for holding and splicing tasks

Compatibility

Designed as an OEM-style industrial masking tape suitable for high-temperature manufacturing processes including powder coating, anodizing, and electroplating operations where clean removal from metal and glass surfaces is required.

Installation Notes

Applied by hand or with a tape dispenser; no special tools required for basic masking work. Ensure the substrate surface is clean, dry, and free of oils or dust before application to achieve full adhesive contact. When used in bake or curing cycles, do not exceed the rated maximum temperature of 400 degrees F. Remove the tape promptly after the bake cycle while the part is still within the rated temperature range to ensure clean release.
