Premium Self-Wound Aluminum Foil 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.
