3M 7000050071 Glass Cloth Tape 361 White 1in X 60yd 7.5 Mil

Product Description

The 3M 7000050071 is a white glass cloth tape — sold as 3M Glass Cloth Tape 361 — featuring a silicone adhesive system and a 7.5 mil total thickness. The woven glass cloth backing delivers strong abrasion resistance and dimensional stability under sustained high-temperature exposure. Silicone adhesive maintains bond integrity where standard acrylic or rubber-based adhesives would fail. Each roll measures 1 inch wide by 60 yards long. This tape is used by HVAC technicians, industrial maintenance crews, and specialty contractors working in environments where thermal resistance and mechanical durability are both required.

Glass Cloth Tape 361 is suited to masking and protection applications during thermal spray operations, as well as high-temperature bundling, wrapping, and sealing tasks in industrial and commercial settings. The tape's flame-resistant properties allow it to be certified to meet FAR 25.853, making it applicable in aerospace and transit-related contexts where flame-spread specifications are enforced. It is sold by the roll with a minimum order quantity of 9 rolls.

Key Features

• 7.5 mil total thickness provides robust backing for demanding masking and protection tasks
• Silicone adhesive system maintains adhesion at elevated temperatures where standard adhesives degrade
• Woven glass cloth backing resists abrasion and tearing during thermal spray and similar high-heat operations
• Can be certified to meet FAR 25.853 flame-resistant specification
• White finish aids visual inspection of tape placement in masking applications
• 1 inch width suits precise masking layouts and component wrapping

Compatibility

Designed for high-temperature masking, protection, and bundling applications in industrial, HVAC, and commercial environments where silicone adhesive and a flame-resistant glass cloth backing are required.

Installation Notes

Application should be performed by qualified technicians familiar with high-temperature taping procedures. Ensure the substrate surface is clean, dry, and free of oils or contaminants before applying. When used in thermal spray masking, confirm tape placement and edge seal before initiating spray operations. Remove tape promptly after the process is complete to minimize any residue transfer from prolonged heat exposure.
