Permanently Seal and Protect
Our 3M™ Glass Cloth Tape 398FR features a white glass-cloth backing designed to provide a clean finished appearance. This tape features a pressure sensitive, acrylic adhesive that adheres to a variety of substrates. It is available on a skip-slit liner for ease of application. Once bonded, this adhesive provides high, secure adhesion for extended periods in a wide range of climate and temperature conditions, including temperatures as high as 250°F/121°C. A blue polyethylene film liner assists with ease of application. This tape features good puncture resistance, high tensile strength and superior abrasion resistance.
3M™ Glass Cloth Tape 398FR meets the flame retardant specifications of F.A.R. Part 25.853(a), F.A.R. Part 25.855(d) and MIL A-3316C 3 13.1 and 3 13.2. 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. This tape meets requirements of and can be qualified to Boeing material specifications BMS 5-146 Type I, Class I, Grade A.
