3M™ 425 Aluminum Foil Tape, 3 Core, 2 x 60 yds, Silver

Soft, thermally conductive aluminum tape dissipates heat over its surface to reduce hot spots and protect the substrate from the effects of high temperatures. Coated with an ultra-high-stick, precision-engineered acrylic adhesive, its capable of withstanding exposure to high humidity as well as very low and very high temperatures, from -65°F to 300°F, while maintaining a very strong, reliable bond.
