3M metal backed tapes

3M™ 363L Built for Heat. Designed for Conversion.

Q: How does this compare to 3M™ GPT020?

While 3M™ GPT020 is used for structural bonding, 3M™ 363L is optimized for thermal shielding and masking , making them complementary in thermal assembly design.

Q: Is this tape flame retardant?

Yes. The glass cloth and aluminum laminate offer flame resistance , commonly used in aerospace and defense manufacturing.

Q: What differentiates 3M™ 363L from standard 363 tape?

363L includes a liner , making it ideal for converting processes like die-cutting, kiss-cutting, and spooling with less waste and cleaner results.

When extreme heat and high-performance sealing go hand in hand, 3M™ High Temperature Aluminum Foil/Glass Cloth Tape 363L delivers. Built with a reinforced aluminum foil/glass cloth laminate, and backed by a heat-resistant silicone adhesive, this industrial-grade tape stands strong through temperatures up to 500°F (260°C) – ideal for high-intensity thermal processes. What sets 363L apart? Its linered construction supports efficient processing, making it easier to die-cut, kiss-cut, or spool without compromising adhesive performance.

At Eko-Tech, we don’t just deliver tape – we customize it. From individual roll lengths to precision die-cut parts, we turn 3M™ 363L into the shielding, sealing, or masking solution you need.
