Blended silicone and rubber adhesive provides higher initial bond to release treated surfaces
Polyester film resists splice failure
Initial bond can be increased by applying heat
Excellent thermal, abrasion and chemical resistance while maintaining flexibility
Confidently Splice Release Treated Paper
Our 3M™ Polyester Splicing Tape 8401 (PDF, 9 Kb) 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°F (-50°C) to 300°F (150°C). Our 3M™ Polyester Splicing Tape 8401 has long service life and is designed to remain firmly adhered and flexible.
