3M™ Glass Cloth Tape 361

3M(TM) 361 Glass Cloth Tape
3M(TM) 361 Glass Cloth Tape
We coated 3M™ Glass Cloth Tape 361 with a silicone adhesive for many applications requiring high-temperature resistance, high adhesion, and a very strong, abrasion-resistant backing that removes cleanly. Our tape can withstand 450⁰F and intermittent temperatures up to 550⁰F or higher, depending on the type and duration of the heat source.
  • Withstands 450 degrees F and intermittent temperatures up to 550 degrees F or higher, depending on heat source
  • Very strong abrasion resistant backing for use as masking protection in thermal spray operations
  • Silicone adhesive provides long aging, good holding power for a wide range of operations
  • Can be certified to meet F.A.R. 25.853, flame resistant specification
  • Used for permanent sealing of high temperature ducts or chambers

Our line of glass cloth tapes combine high temperature resistance, high adhesion, and a very strong, abrasion resistant backing. The glass cloth backing resists shrinking, rotting, or burning – providing exceptional stability in harsh environments.

3M™ Glass Cloth Tape 361 features a glass cloth backing with pressure-sensitive silicone adhesive. The tape is primarily used in the aerospace, automotive, military, space, roofing, nuclear, specialty vehicle and ship building industries for fabric splicing, seaming and sealing panels, heavy duty masking, bundling, holding, harness wrapping and welding backup.

Application Ideas

  • High temperature applications requiring high tensile strength, good holding power and abrasion resistance
  • Permanent sealing of high temperature ducts or chambers
  • As a back up strip for submerged arc welding
  • Applications requiring heat treatment followed by clean removal of the tape with little or no stain
