3M™ General Purpose Glass Cloth Tape 3615 is a general purpose, easy unwind tape coated with a silicone adhesive. It is ideally suited for many applications requiring high adhesion and high-temperature resistance. With a very strong, abrasion-resistant backing this tape performs exceptionally well in a many situations and environments.
Withstands up to 450°F/232°C and intermittent temperatures up to 550°F/288°C or higher, depending on the heat source
Tape performs under a variety of conditions with strong abrasion and puncture resistance
Glass cloth for high tensile strength to provide a permanent seal
Silicone adhesive for long aging, good holding power for a wide operating range to help increase productivity
High Temperature Performance
We've designed 3M™ General Purpose Glass Cloth Tape 3615 to excel in a wide variety of applications. This general purpose tape is ideal for high temperature applications requiring high tensile strength and good holding power. It performs under a wide temperature range (from -65°F/-54°C to 450°F/232°C) and can withstand intermittent temperatures up to 550°F/288°C or higher, depending on the type and duration of the heat source. The glass cloth backing offers superior abrasion and puncture resistance, allowing it to withstand rugged applications. With an easy unwind you'll find this tape easy to handle during application.
General applications in the aerospace, automotive, transportation, general industrial, construction and marine industries
Permanent sealing of high temperature ducts or chambers
Back-up strip for submerged arc welding
General splicing, seaming and sealing applications
Bundling, holding and harness wrapping applications
Protect surfaces against abrasion
Long Aging Holding Power
This tape features a pressure sensitive silicone adhesive that is ideal for high temperatures allowing it to perform within a wide temperature range. High heat resistance helps prevent failure from softening or oozing of the adhesive. The long aging properties of the adhesive allow the tape to remain adhered and flexible. Silicone adhesive sticks well to difficult surfaces such as silicone liners and silicone coated surfaces. It also works well in composite bonding applications as it sticks well to molds treated with a release agent.
