3M 7000049778 Masking Tape 1 in 72 Yd Blue Silicone

Product Description

The 3M 7000049778 is a polyester film masking tape designed for applications that demand clean adhesion and reliable performance across a range of trade and industrial tasks. It measures 1 inch wide and 72 yards long, with a 2.4 mil thick polyester film backing and a silicone-based adhesive. The silicone adhesive provides a firm bond while allowing for clean removal without leaving residue on most surfaces. At 0.34 pounds per roll, it is easy to handle and store. This tape is suited for HVAC, electrical, plumbing, and general trade applications where a durable, conformable masking tape is required.

This tape is appropriate for use in residential and commercial settings. Its polyester film construction holds up in environments where paper-based tapes may fail, such as areas with moisture or surface irregularities. Tradespeople use it for masking during painting, surface protection during installation work, labeling, bundling, and general-purpose holding tasks on jobsites. The blue color allows for easy visual identification when multiple tape types are in use on the same project.

Installation Notes

Apply to clean, dry surfaces free of dust, oil, and loose material for best adhesion. Silicone adhesive is intended for temporary masking and surface protection — do not use as a permanent fastening solution. Remove tape promptly after use to reduce the chance of adhesive transfer, particularly on painted or finished surfaces. No special tools are required for application or removal.
