PRODUCT FAQ

  1. What is 3M™ Thermosetable Glass Cloth Tape 3650 used for?

    Great question! This tape is mainly used for applications needing high heat resistance, like electrical insulation and coil wrapping. It’s also popular in various aerospace and industrial uses that require durability and strength under heat.

  2. Is the tape easy to use or cut to size?

    Absolutely! The glass cloth backing makes it strong but still flexible, so you can easily trim it with scissors or a blade to fit your exact needs. It’s designed to be user-friendly while providing reliable performance.

  3. Can the tape withstand high temperatures?

    Yes, it sure can! This glass cloth tape is designed specifically for thermosetting applications and will perform well at elevated temperatures—making it ideal where regular tapes might fail due to heat exposure.

3M™ Thermosetable Glass Cloth Tape 3650: Engineered for High-Performance Splicing and Insulation

3M™ Thermosetable Glass Cloth Tape 3650 is a premium white glass cloth tape designed to meet the rigorous demands of industrial splicing and insulation applications. Featuring a thermosetable rubber adhesive, this tape is specifically engineered for use on textured or rough surfaces, making it an excellent choice for materials that require exceptional tensile strength, even at elevated temperatures. The conformable glass cloth backing not only delivers impressive tensile strength but also offers outstanding resistance to solvents, abrasion, and punctures. Unlike many other tapes, it will not shrink or rot over time, ensuring long-lasting durability in challenging environments.

This versatile tape is capable of performing reliably across a broad temperature range, from as low as 40°F (4°C) up to 450°F (232°C). 3M™ Thermosetable Glass Cloth Tape 3650 is the linered version of the well-known 3M™ Thermosetable Glass Cloth Tape 365, making it particularly suitable for die-cutting applications where precision and clean handling are essential.

Advanced Adhesive Technology for Superior Performance

The rubber adhesive on 3M™ Thermosetable Glass Cloth Tape 3650 provides excellent initial adhesion and high tack, ensuring a secure bond upon application. When exposed to a thermosetting process—typically achieved by applying heat or ironing the tape after placement—the adhesive cross-links, resulting in enhanced bond strength and increased heat resistance. The level of adhesion can be optimized by adjusting the time, temperature, and pressure during the heat application process, allowing for tailored performance to meet specific project requirements.

Recommended Applications
  • Splicing and insulating applications that demand high tensile strength at elevated temperatures
  • Corrosion-resistant wrapping for stainless steel hot air ducts
  • Splicing materials with rough surfaces or low internal strength, such as roofing felt, fiberglass, or textiles
  • Die-cut applications requiring a linered tape for precise and efficient processing
