Aerospace Speed Tape Specifications: FAR 25.853(a) SAE AMS-T-23397B (supersedes MIL-T-23397A) L-T-80B Tested in accordance with UL 723 Aircraft Speed Tape Adhesive: acrylic Core: 3" diameter Masking in paint stripping and electro-plating Insulation patch, seal and repair Made in USA   Polyken 345SW Premium Self-Wound Aluminum Foil Tape Aircraft Speed Tape Has many uses in aviation, general industrial and OEM industries. This is a heavy-duty dead soft aluminum foil tape that's used for aircraft masking and sealing applications. UL and FAR certified, it acts as a heat shield to minimize heat transfer and provides an effective barrier to moisture, air and corrosion. Polyken 345SW Premium Self-Wound tape has a smooth, easy unwind, and because there is no release liner, there's less waste. This aluminum foil tape conforms well to contours and irregular surfaces and bonds to most substrates. Its acrylic adhesive coating is resistant to solvents and performs well in high temperatures. The tape can also be cleanly and easily removed from most surfaces, leaving no residue.
