Glass Cloth Thermal Spray Masking Tape (80907)

A 7.6 mil electrical grade, woven fiberglass cloth, coated on one side with a high performance silicone adhesive.  This pressure sensitive tape is designed for use in strategic masking off of areas for thermal spray / plasma spray operations. It can withstand exposure to temperatures up to and in excess of 500°F.  The high tensile strength and dimensional stability of the glass cloth backing are combined with a high quality silicone adhesive to produce a tape that is conformable, chemical and solvent resistant, and printable.  The tape is wound on a 3” white plastic core.


  • Masking applications for thermal spray and plasma spray.
  • Used for coil wrap, crossover insulation, and coil banding. 
  • For insulation of electrical apparatus in military equipment.
  • To seal / bundle non-electrical applications where flame retardency or high heat resistance is required.
