3M™ Glass Cloth Tape 398FR is a flame retardant solution for many aerospace and MRO applications. It features a pressure sensitive acrylic adhesive that bonds on contact to a variety of substrates. This high adhesion bond will remain secure for extended periods of time while resisting wear and spills.

Flame Retardant Solution Our 3M™Glass Cloth Tape 398FR is a white, glass cloth film tape with an acrylic adhesive that provides superior product performance and flame retardant properties. It features a 5.0 mil backing and a blue polyethylene film liner for ease of application. This tape is durable and has a high temperature resistance (up to 250°F/121°C). It also features good puncture resistance, high tensile strength and superior abrasion resistance. The white color ensures a clean and appealing finished product. Combined, these qualities make it is an ideal choice for use in many aerospace applications, including aircraft repair. Recommended Applications Sealing thermal and acoustic insulation panels where high adhesion and flame retardancy are needed Aircraft window sealing, duct sealing and seat repair Protection of wire harnesses, electrical cables or hoses from high temperature extremes and abrasion Various marine applications General industrial and MRO applications Superior Adhesion with Acrylic This tape features an acrylic adhesive that adheres immediately on contact to a variety of substrates. Once bonded this adhesive will provide high, secure adhesion for extended periods. This adhesive maintains adhesion in climate and temperature change variations. Meeting Industry Demands 3M™ Glass Cloth Tape 398FR meets flame retardancy requirements of F.A.R. Part 25.853(a) and F.A.R. Part 25.855 (d); Boeing material specification BMS 5-146 Type I, Class I, Grade A; and Airbus Specification ABS 5649. It is EU compliant per directive 2003/11 EC of the European Parliament and the Council of February 6, 2003, amending Council Directive 76/769/EEC which restricts the use of penta-BDE and octa-BDE flame retardants.
