3M polyester splicing tape 8401 is a single coated tape designed for use with many release coated papers. It features a blended silicone and rubber adhesive and a polyester film to resist splice failure. Increased initial bond can be achieved by applying heat. Our 3M polyester splicing tape 8401 is a thin, conformable polyester tape ideal for masking in high temperature applications and adheres well to silicone coated surfaces. This tape also excels in permanent splicing operations on silicone liners, papers and films subject to high temperatures. The cream color makes for easier identification. The pressure sensitive silicone rubber adhesive performs under a broad range of temperatures ranging from -60 to 300 deg F. Our 3M polyester splicing tape 8401 has long service life and is designed to remain firmly adhered and flexible.
