    Details
    • 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

    3M™ Polyester Tape 8403 is a translucent green polyester tape with a pressure sensitive silicone adhesive. It can withstand high temperatures and caustic environments, yet still removes without unwanted residue to eliminate time consuming clean-up. This tape meets demanding applications common to the graphic arts, photography, metal finishing and electronic industries.

    Resilient Performance
    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.
