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.
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.
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.
