Designed for damping resonant vibrations of thin sheet metal, this tape is a pressure sensitive, specially compounded polyurethane damping foam with an aluminum foil backing. The adhesive on the foam is protected by a peel-off paper covering. It is an excellent insulator for conducted heat and is an excellent heat reflector. Fire-resistant and self-extinguishing per FAA test procedure. Excellent moisture resistance. Resistant to most solvents. Easily applied with only hand pressure for a permanent bond even on rough, irregular surfaces. Used extensively in commercial aircraft and highly recommended for metal home-builts. Apply to firewall, fuselage - anywhere a vibration problem exists. Wt. 4 oz./sq. ft., 1/4" thick.
