Shurtape AF-075 Aluminum Foil Tape is a 3 mil dead-soft linerless aluminum foil tape which is designed to resist extreme temperature fluctuations. It adheres to its own backing and also particularly well on irregular surfaces. Used to create vapor barriers and waterproof seals; to reflect and dissipate heat; and for masking off areas when painting and electroplating. The tape is coated with an agressive acrylic adhesive and meets the L-T-80B; SAE-AMS-T-23397 (replaced MIL-T-23397B - canceled 9/21/98) standards. Please note AF-075 typically ships on a plain white core (not Shurtape-branded).
