3M™ Polyester Tape 8403, Green, 2 3/4 in x 72 yd, 2.4 mil, 12 Rolls/Case
- 3M ID 7010372866
Details
Highlights
- Removes cleanly and remains flexible for continued performance
- Excellent temperature and good abrasion resistance
- High tear resistance and tensile strength ensures tape can withstand rugged processes while maintaining long-term aging
- Adheres well to silicone and is chemical resistant, an ideal choice for acid baths and exposure to caustic processes
- Thin, low caliper, but high strength polyester film less likely to interfere with machinery
- Translucent green backing is easily identifiable for splicing applications
For anodizing, composite bonding and splicing, use 3M™ Polyester Tape 8403. This translucent green tinted tape is coated with a silicone adhesive that bonds well on difficult surfaces, including silicone coated papers and films. It is chemical resistant and performs under a wide range of temperatures and environments. This tape is a thicker version of 3M™ Polyester Tape 8402.
Our 3M™ Polyester Film Tape 8403 is a popular choice for a variety of web splicing, masking and holding applications, particularly those needing good chemical resistance or adhesion to silicone. The thin, high tensile strength polyester backing is abrasion and solvent resistant while featuring a relatively low caliper thickness that is less likely to interfere with machinery processes.
Recommended Applications
Protective overall mask on panels to mild caustic and acid bath etching
Prevent scratching during handling
Holding parts or vacuum bags during bonding processes
Mask for metal in acid or caustic chemical milling baths
Masking parts in anodizing processes
Splicing of silicone coated papers and films
Paint masking of materials subjected to high temperatures
Butt splicing and core starting
Masking the edges of overlap seams in metal bonding process where excess epoxy can overflow
Excellent Adhesion with Silicone
This tape features a pressure sensitive silicone adhesive that is ideal for high temperatures, allowing this tape to perform within a wide temperature range (-60°F/-50°C to 400°F/204°C). The adhesive is long-aging to allow this tape to remain adhered and flexible for up to 3 hours while being used in an autoclave, as flash breaker tape or as masking for acid and caustic baths, among other applications. When finished this tape removes cleanly and easily to eliminate time consuming cleaning processes.
