3M 398FR Glass Cloth Tape features a white glass-cloth backing coated with an acrylic adhesive, ensuring strong adhesion to a variety of substrates. The tape includes a skip-slit blue polyethylene film liner for easy application. Once bonded, it provides secure adhesion that withstands a wide range of climate and temperature conditions, including temperatures up to 250°F (121°C). Additionally, it meets F.A.R. flame retardancy requirements, making it an ideal flame-retardant solution for aerospace and MRO applications.
1. Durable backing provides abrasion and puncture resistance, ensuring long-term aging performance in aerospace applications.
2. Acrylic adhesive offers excellent long-aging properties, making it ideal for many permanent applications.
3. Temperature resistance ranges from -20ºF (-29ºC) to 250ºF (121ºC), providing reliable performance in diverse conditions.
4. Compliance with F.A.R. Part 25.853(a) and F.A.R. Part 25.855(d) ensures adherence to stringent safety standards.
5. Meets Boeing material specification BMS 5-146 Type I, Class I, Grade A, guaranteeing quality and reliability.
6. High conformability allows the tape to bond effectively over difficult textures and uneven or curved surfaces.
