Product Description

The 3M 7000049004 is a white glass cloth tape with an acrylic adhesive system, sold under the 398FR designation for applications that demand high adhesion, flame retardant performance, and an abrasion-resistant backing. The tape measures 3 inches wide by 36 yards long and weighs 2.68 pounds per roll. It is engineered to meet Federal Aviation Regulation (FAR) flame retardancy requirements, making it a recognized choice where fire-resistant sealing and surface protection are required in demanding environments. Installation is typically performed by aviation maintenance technicians and other qualified trade professionals working in regulated service settings.

The 398FR tape is designed for aircraft maintenance and repair applications where flame retardant properties and a durable, abrasion-resistant backing are required by specification. Its acrylic adhesive provides strong, reliable adhesion to a variety of substrates encountered in these environments. The tape is supplied in roll form and is suited for sealing, bundling, and surface protection tasks that must meet FAR flame retardancy standards. It may also find use in other industrial or trade settings where a flame retardant glass cloth tape is specified.
