3M Glass cloth tape 361

3M Glass Cloth Tape 361 is coated with a silicone adhesive for many applications requiring high-temperature resistance, high adhesion, and a very strong, abrasion-resistant backing.
Constructed with a woven fiberglass backing, 3M Glass Cloth Tape 361 features a pressure-sensitive silicone adhesive for applications requiring high-temperature resistance, high adhesion, and clean removal.
It is often used for high-temperature applications such as sealing ducts and as a backup strip for submerged arc welding.

3M Glass cloth tape 361 Features

Strong abrasion-resistant backing provides strength for bundling, harnessing, and protection applications requiring high tensile strength
Silicone adhesive provides good holding power and clean removal across a wide range of temperatures
Withstands temperatures from -65°F/-54°C to 450°F/232°C and intermittent temperatures up to 550°F/288°C or higher, depending on the type and duration of the heat source
Can be certified to meet F.A.R. 25.853, flame resistant specification
Used for permanent sealing of high-temperature ducts or chambers
Can be certified to meet FAR 25.853 (a) Appendix F Part I (a) (1) (ii), flame resistant specification.
Can withstand intermittent temperatures up to 550°F (288°C) or higher, depending upon the type and duration of the heat source.
Continuous exposure to temperatures above 450°F (232°C) will gradually degrade the adhesive causing a loss of tape adhesion and darkening the glass cloth backing.

3M Glass cloth tape 361 Applications

Permanent sealing of high-temperature ducts or chambers
Applications requiring heat treatment followed by clean removal of the tape with little or no stain
Protect surfaces against abrasion
High-temperature masking
Bundling, holding, and wire harnessing
