3M™ Polyester Tape 8403, Green, 51 mm x 66 m, 0.061 mm

Polyester film backing with a translucent green pigmented silicone adhesive.

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.
